Backend capabilities

Methods

impl BackendFlags

pub const HAS_GAMEPAD: BackendFlags

Backend supports gamepad and currently has one connected

pub const HAS_MOUSE_CURSORS: BackendFlags

Backend supports honoring get_mouse_cursor value to change the OS cursor shape

pub const HAS_SET_MOUSE_POS: BackendFlags

Backend supports io.want_set_mouse_pos requests to reposition the OS mouse position.

Only used if ConfigFlags::NavEnableSetMousePos is set.

pub const RENDERER_HAS_VTX_OFFSET: BackendFlags

Backend renderer supports DrawCmd::vtx_offset.

This enables output of large meshes (64K+ vertices) while still using 16-bits indices.

pub const fn empty() -> BackendFlags

Returns an empty set of flags

pub const fn all() -> BackendFlags

Returns the set containing all flags.

pub const fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u32) -> Option<BackendFlags>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub const fn from_bits_truncate(bits: u32) -> BackendFlags

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub const fn intersects(&self, other: BackendFlags) -> bool

Returns true if there are flags common to both self and other.

pub const fn contains(&self, other: BackendFlags) -> bool

Returns true all of the flags in other are contained within self.

pub fn insert(&mut self, other: BackendFlags)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: BackendFlags)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: BackendFlags)

Toggles the specified flags in-place.

pub fn set(&mut self, other: BackendFlags, value: bool)

Inserts or removes the specified flags depending on the passed value.
