Enum ContainerFormat 

pub enum ContainerFormat {
    Png,
    Webp,
    Avif,
}

Identifies one of the supported image container formats for the runtime-dispatched rgb_to_container entry point.

All three variants are always present in the enum so callers can parse user-supplied format names regardless of which cargo features were enabled at compile time. Encoding into a format whose feature is not enabled returns ContainerError::Unsupported.

Variants

Png

PNG.

Webp

Lossless WebP.

Avif

AVIF (encode-only).

Implementations

impl ContainerFormat

pub const ALL: [Self; 3]

All variants, in declaration order.

pub const fn name(self) -> &'static str

Canonical lowercase name ("png" / "webp" / "avif").

pub const fn mime_type(self) -> &'static str

IANA MIME type for the format.

pub const fn is_enabled(self) -> bool

Whether the encoder for this format was compiled in at build time.

Trait Implementations

impl Clone for ContainerFormat

fn clone(&self) -> ContainerFormat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContainerFormat

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

Formats the value using the given formatter.

impl Display for ContainerFormat

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

Formats the value using the given formatter.

impl FromStr for ContainerFormat

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses case-insensitively. Accepts the canonical lowercase names as well as the image/<name> MIME shorthand.

type Err = ParseContainerFormatError

The associated error which can be returned from parsing.

impl Hash for ContainerFormat

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ContainerFormat

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