Struct OpenGraphImage 

pub struct OpenGraphImage { /* private fields */ }

Open Graph image metadata.

Implementations

impl OpenGraphImage

pub fn new(value: impl AsRef<str>) -> Result<Self, MetadataValueError>

Creates an Open Graph image from a URL-like string.

Errors

Returns MetadataValueError::InvalidUrl when the URL shape is unsupported.

pub fn with_alt(self, alt: impl AsRef<str>) -> Result<Self, MetadataValueError>

Sets alternative text.

Errors

Returns MetadataValueError::Empty when the alt text is empty.

pub fn with_dimensions( self, width: u32, height: u32, ) -> Result<Self, MetadataValueError>

Sets image dimensions.

Errors

Returns MetadataValueError::InvalidImageDimensions when either dimension is zero.

pub fn url(&self) -> &str

Returns the image URL.

Trait Implementations

impl Clone for OpenGraphImage

fn clone(&self) -> OpenGraphImage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OpenGraphImage

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

Formats the value using the given formatter.

impl PartialEq for OpenGraphImage

fn eq(&self, other: &OpenGraphImage) -> 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.
