Enum AssetSourceId

pub enum AssetSourceId<'a> {
    Default,
    Name(CowArc<'a, str>),
}

A reference to an “asset source”, which maps to an AssetReader and/or AssetWriter.

• AssetSourceId::Default corresponds to “default asset paths” that don’t specify a source: /path/to/asset.png
• AssetSourceId::Name corresponds to asset paths that do specify a source: remote://path/to/asset.png, where remote is the name.

Variants

Default

The default asset source.

Name(CowArc<'a, str>)

A non-default named asset source.

Implementations

impl<'a> AssetSourceId<'a>

pub fn new(source: Option<impl Into<CowArc<'a, str>>>) -> AssetSourceId<'a>

Creates a new AssetSourceId

pub fn as_str(&self) -> Option<&str>

Returns None if this is AssetSourceId::Default and Some containing the name if this is AssetSourceId::Name.

pub fn into_owned(self) -> AssetSourceId<'static>

If this is not already an owned / static id, create one. Otherwise, it will return itself (with a static lifetime).

pub fn clone_owned(&self) -> AssetSourceId<'static>

Clones into an owned [AssetSourceId<'static>]. This is equivalent to .clone().into_owned().

impl AssetSourceId<'static>

pub fn as_static(self) -> Self

Indicates this AssetSourceId should have a static lifetime.

pub fn from_static(value: impl Into<Self>) -> Self

Constructs an AssetSourceId with a static lifetime.

Trait Implementations

impl<'a> Clone for AssetSourceId<'a>

fn clone(&self) -> AssetSourceId<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for AssetSourceId<'a>

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

Formats the value using the given formatter.

impl<'a> Default for AssetSourceId<'a>

fn default() -> AssetSourceId<'a>

Returns the “default value” for a type.

impl<'a> Display for AssetSourceId<'a>

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

Formats the value using the given formatter.

impl<'a, 'b> From<&'a AssetSourceId<'b>> for AssetSourceId<'b>

fn from(value: &'a AssetSourceId<'b>) -> Self

Converts to this type from the input type.

impl<'a> From<&'a str> for AssetSourceId<'a>

fn from(value: &'a str) -> Self

Converts to this type from the input type.

impl<'a> From<Option<&'a str>> for AssetSourceId<'a>

fn from(value: Option<&'a str>) -> Self

Converts to this type from the input type.

impl From<String> for AssetSourceId<'static>

fn from(value: String) -> Self

Converts to this type from the input type.

impl<'a> Hash for AssetSourceId<'a>

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<'a> PartialEq for AssetSourceId<'a>

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