Struct gfx_core::memory::Access

pub struct Access { /* fields omitted */ }

[−] Expand description

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).

Implementations

impl Access[−]

pub const READ: Access[−][−]

Read access

pub const WRITE: Access[−][−]

Write access

pub const RW: Access[−][−]

Full access

pub const fn empty() -> Access[−]

Returns an empty set of flags

pub const fn all() -> Access[−]

Returns the set containing all flags.

pub const fn bits(&self) -> u8[−]

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u8) -> Option<Access>[−]

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

pub const fn from_bits_truncate(bits: u8) -> Access[−]

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

pub const unsafe fn from_bits_unchecked(bits: u8) -> Access[−]

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

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: Access) -> bool[−]

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

pub const fn contains(&self, other: Access) -> bool[−]

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

pub fn insert(&mut self, other: Access)[−]

Inserts the specified flags in-place.

pub fn remove(&mut self, other: Access)[−]

Removes the specified flags in-place.

pub fn toggle(&mut self, other: Access)[−]

Toggles the specified flags in-place.

pub fn set(&mut self, other: Access, value: bool)[−]

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