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:
This information is used to create resources (see gfx::Factory).
Methods
impl Access
pub const READ: Access
READ: Access = Access{bits: 1,}
Read access
pub const WRITE: Access
WRITE: Access = Access{bits: 2,}
Write access
pub const RW: Access
RW: Access = Access{bits: 3,}
Full access
pub fn empty() -> Access
Returns an empty set of flags.
pub fn all() -> Access
Returns the set containing all flags.
pub 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 fn from_bits_truncate(bits: u8) -> Access
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
pub fn is_empty(&self) -> bool
Returns true if no flags are currently stored.
pub fn is_all(&self) -> bool
Returns true if all flags are currently set.
pub fn intersects(&self, other: Access) -> bool
Returns true if there are flags common to both self and other.
pub 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.
