Struct LayerMediaType 

pub struct LayerMediaType(/* private fields */);

An OCI layer media type.

Implementations

impl LayerMediaType

pub fn new(media_type: OciMediaType) -> Result<LayerMediaType, LayerError>

Creates a layer media type after checking that it is layer-shaped.

pub const fn tar() -> LayerMediaType

Returns an uncompressed tar layer media type.

pub const fn gzip_tar() -> LayerMediaType

Returns a gzip-compressed tar layer media type.

pub const fn zstd_tar() -> LayerMediaType

Returns a zstd-compressed tar layer media type.

pub const fn media_type(&self) -> &OciMediaType

Returns the underlying media type.

pub const fn compression(&self) -> LayerCompression

Returns the compression implied by the media type.

Trait Implementations

impl Clone for LayerMediaType

fn clone(&self) -> LayerMediaType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LayerMediaType

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

Formats the value using the given formatter.

impl Display for LayerMediaType

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

Formats the value using the given formatter.

impl Hash for LayerMediaType

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

where __H: Hasher,

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 Ord for LayerMediaType

fn cmp(&self, other: &LayerMediaType) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for LayerMediaType

fn eq(&self, other: &LayerMediaType) -> 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 LayerMediaType

fn partial_cmp(&self, other: &LayerMediaType) -> 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.
