Struct BackendCapabilities 

pub struct BackendCapabilities { /* private fields */ }

The capabilities advertised by one backend.

The set is deterministic so missing-capability diagnostics and tests are stable across platforms. Use named builders rather than positional booleans when constructing it.

Implementations

impl BackendCapabilities

pub const fn new() -> Self

Creates an empty capability set.

pub fn from_capabilities<I>(capabilities: I) -> Self

where I: IntoIterator<Item = BackendCapability>,

Creates a capability set from an iterable collection.

pub fn with(self, capability: BackendCapability) -> Self

Returns a copy with one capability added.

pub fn supports(&self, capability: BackendCapability) -> bool

Returns whether this backend advertises a capability.

pub fn iter(&self) -> impl Iterator<Item = &BackendCapability>

Returns capabilities in deterministic order.
