Enum wgpu::core::resource::BufferMapAsyncStatus

#[repr(C)]
pub enum BufferMapAsyncStatus {
    Success = 0,
    AlreadyMapped = 1,
    MapAlreadyPending = 2,
    Error = 3,
    Aborted = 4,
    ContextLost = 5,
    Invalid = 6,
    InvalidRange = 7,
    InvalidAlignment = 8,
    InvalidUsageFlags = 9,
}

The status code provided to the buffer mapping callback.

This is very similar to BufferAccessResult, except that this is FFI-friendly.

Variants

Success = 0

The Buffer is sucessfully mapped, get_mapped_range can be called.

All other variants of this enum represent failures to map the buffer.

AlreadyMapped = 1

The buffer is already mapped.

While this is treated as an error, it does not prevent mapped range from being accessed.

MapAlreadyPending = 2

Mapping was already requested.

Error = 3

An unknown error.

Aborted = 4

Mapping was aborted (by unmapping or destroying the buffer before mapping happened).

ContextLost = 5

The context is Lost.

Invalid = 6

The buffer is in an invalid state.

InvalidRange = 7

The range isn’t fully contained in the buffer.

InvalidAlignment = 8

The range isn’t properly aligned.

InvalidUsageFlags = 9

Incompatible usage flags.
