Struct LinkPreviewOptions

pub struct LinkPreviewOptions {
    pub is_disabled: Option<bool>,
    pub prefer_large_media: Option<bool>,
    pub prefer_small_media: Option<bool>,
    pub show_above_text: Option<bool>,
    pub url: Option<String>,
}

Represents the options used for link preview generation.

Fields

is_disabled: Option<bool>

Whether the link preview is disabled.

prefer_large_media: Option<bool>

Whether the media in the link preview is suppposed to be enlarged.

prefer_small_media: Option<bool>

Whether the media in the link preview is suppposed to be shrunk.

show_above_text: Option<bool>

Whether the link preview must be shown above the message text.

url: Option<String>

URL to use for the link preview.

Implementations

impl LinkPreviewOptions

pub fn with_is_disabled(self, value: bool) -> LinkPreviewOptions

Sets a new value for the is_disabled flag.

Arguments

• value - Whether the link preview is disabled.

pub fn with_prefer_large_media(self, value: bool) -> LinkPreviewOptions

Sets a new value for the prefer_large_media flag.

Arguments

• value - Whether the media in the link preview is suppposed to be enlarged; ignored if the URL isn’t explicitly specified or media size change isn’t supported for the preview.

pub fn with_prefer_small_media(self, value: bool) -> LinkPreviewOptions

Sets a new value for the prefer_small_media flag.

Arguments

• value - Whether the media in the link preview is suppposed to be shrunk; ignored if the URL isn’t explicitly specified or media size change isn’t supported for the preview.

pub fn with_show_above_text(self, value: bool) -> LinkPreviewOptions

Sets a new value for the show_above_text flag.

Arguments

• value - Whether the link preview must be shown above the message text; otherwise, the link preview will be shown below the message text.

pub fn with_url<T>(self, value: T) -> LinkPreviewOptions

where T: Into<String>,

Sets a new URL.

Arguments

• value - URL to use for the link preview.

If empty, then the first URL found in the message text will be used.

Trait Implementations

impl Clone for LinkPreviewOptions

fn clone(&self) -> LinkPreviewOptions

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LinkPreviewOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for LinkPreviewOptions

fn default() -> LinkPreviewOptions

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LinkPreviewOptions

fn deserialize<__D>( __deserializer: __D, ) -> Result<LinkPreviewOptions, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for LinkPreviewOptions

fn eq(&self, other: &LinkPreviewOptions) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for LinkPreviewOptions

fn partial_cmp(&self, other: &LinkPreviewOptions) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for LinkPreviewOptions

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
