Struct gfx::memory::Access

pub struct Access { /* fields omitted */ }

Flags providing information about the type of memory access to a resource.

An Access value can be a combination of the the following bit patterns:

• READ
• WRITE
• Or RW which is equivalent to READ and WRITE.

This information is used to create resources (see gfx::Factory).

Methods

impl Access

const READ: Access

READ: Access = Access{bits: 1,}

const WRITE: Access

WRITE: Access = Access{bits: 2,}

const RW: Access

RW: Access = Access{bits: 3,}

fn empty() -> Access

Returns an empty set of flags.

fn all() -> Access

Returns the set containing all flags.

fn bits(&self) -> u8

Returns the raw value of the flags currently stored.

fn from_bits(bits: u8) -> Option<Access>

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

fn from_bits_truncate(bits: u8) -> Access

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

fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

fn is_all(&self) -> bool

Returns true if all flags are currently set.

fn intersects(&self, other: Access) -> bool

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

fn contains(&self, other: Access) -> bool

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

fn insert(&mut self, other: Access)

Inserts the specified flags in-place.

fn remove(&mut self, other: Access)

Removes the specified flags in-place.

fn toggle(&mut self, other: Access)

Toggles the specified flags in-place.

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

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