Enum AccessType 

pub enum AccessType {
    None,
    ShaderRead,
    ShaderWrite,
    TransferSrc,
    TransferDst,
    HostRead,
    HostWrite,
}

Describes the type of resource access for barrier tracking.

Variants

None

No access (initial state).

ShaderRead

Read-only access from a shader.

ShaderWrite

Write access from a shader (compute or fragment).

TransferSrc

Transfer source (copy from).

TransferDst

Transfer destination (copy to).

HostRead

Host read (CPU readback).

HostWrite

Host write (CPU upload).

Trait Implementations

impl Clone for AccessType

fn clone(&self) -> AccessType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AccessType

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

Formats the value using the given formatter.

impl Display for AccessType

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

Formats the value using the given formatter.

impl Hash for AccessType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for AccessType

fn eq(&self, other: &AccessType) -> 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.
