Expand description

Internal error type for the wasi-common crate. Contains variants of the WASI $errno type are added according to what is actually used internally by the crate. Not all values are represented presently.

Variants

`WouldBlk`

Errno::WouldBlk: Would block

`Noent`

Errno::Noent: No such file or directory

`TooBig`

Errno::TooBig: Argument list too long

`Badf`

Errno::Badf: Bad file descriptor

`Exist`

Errno::Exist: File exists

`Ilseq`

Errno::Ilseq: Illegal byte sequence

`Inval`

Errno::Inval: Invalid argument

`Io`

Errno::Io: I/O error

`Nametoolong`

Errno::Nametoolong: Filename too long

`Notdir`

Errno::Notdir: Not a directory or a symbolic link to a directory.

`Notsup`

Errno::Notsup: Not supported, or operation not supported on socket.

`Overflow`

Errno::Overflow: Value too large to be stored in data type.

`Range`

Errno::Range: Result too large

`Spipe`

Errno::Spipe: Invalid seek

`Perm`
