Struct ImageVariant 

pub struct ImageVariant {
    pub path: String,
    pub hash: DocumentId,
    pub width: u32,
    pub height: u32,
    pub scale: f32,
    pub size: u64,
}

A resolution variant of an image for responsive display.

Fields

path: String

Path within the archive.

hash: DocumentId

Content hash for verification.

width: u32

Image width in pixels.

height: u32

Image height in pixels.

scale: f32

Scale factor (e.g., 1.0 for 1x, 2.0 for 2x, 3.0 for 3x).

size: u64

File size in bytes.

Implementations

impl ImageVariant

pub fn new(path: impl Into<String>, width: u32, height: u32, scale: f32) -> Self

Create a new image variant.

pub fn with_hash(self, hash: DocumentId) -> Self

Set the content hash.

pub const fn with_size(self, size: u64) -> Self

Set the file size.

pub fn scale_1x(path: impl Into<String>, width: u32, height: u32) -> Self

Create a 1x variant.

pub fn scale_2x(path: impl Into<String>, width: u32, height: u32) -> Self

Create a 2x (Retina) variant.

pub fn scale_3x(path: impl Into<String>, width: u32, height: u32) -> Self

Create a 3x variant.

Trait Implementations

impl Clone for ImageVariant

fn clone(&self) -> ImageVariant

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ImageVariant

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ImageVariant

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ImageVariant

fn eq(&self, other: &ImageVariant) -> 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 Serialize for ImageVariant

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
