Enum wgpu_core::resource::BufferMapAsyncStatus

#[repr(C)]
pub enum BufferMapAsyncStatus {
    Success,
    AlreadyMapped,
    MapAlreadyPending,
    Error,
    Aborted,
    ContextLost,
    Invalid,
    InvalidRange,
    InvalidAlignment,
    InvalidUsageFlags,
}

The status code provided to the buffer mapping callback.

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

Variants

Success

The Buffer is sucessfully mapped, get_mapped_range can be called.

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

AlreadyMapped

The buffer is already mapped.

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

MapAlreadyPending

Mapping was already requested.

Error

An unknown error.

Aborted

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

ContextLost

The context is Lost.

Invalid

The buffer is in an invalid state.

InvalidRange

The range isn’t fully contained in the buffer.

InvalidAlignment

The range isn’t properly aligned.

InvalidUsageFlags

Incompatible usage flags.
