Implementations

impl<Overrides, Base> OverlayResourceProvider<Overrides, Base>

pub fn new(overrides: Overrides, base: Base) -> Self

Create a provider that checks overrides before base.

pub fn overrides(&self) -> &Overrides

Return a reference to the override provider.

pub fn base(&self) -> &Base

Return a reference to the base provider.

Trait Implementations

impl<Overrides: Clone, Base: Clone> Clone for OverlayResourceProvider<Overrides, Base>

fn clone(&self) -> OverlayResourceProvider<Overrides, Base>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Overrides: Debug, Base: Debug> Debug for OverlayResourceProvider<Overrides, Base>

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

Formats the value using the given formatter.

impl<Overrides: Eq, Base: Eq> Eq for OverlayResourceProvider<Overrides, Base>

impl<Overrides: PartialEq, Base: PartialEq> PartialEq for OverlayResourceProvider<Overrides, Base>

fn eq(&self, other: &OverlayResourceProvider<Overrides, Base>) -> 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.
