Enum FileDescriptor

pub enum FileDescriptor {
    StdIn,
    StdOut,
    StdErr,
    HintRead,
    HintWrite,
    PreimageRead,
    PreimageWrite,
    Wildcard(usize),
}

File descriptors available to the client within the FPVM kernel.

Variants

StdIn

Read-only standard input stream.

StdOut

Write-only standaard output stream.

StdErr

Write-only standard error stream.

HintRead

Read-only. Used to read the status of pre-image hinting.

HintWrite

Write-only. Used to provide pre-image hints

PreimageRead

Read-only. Used to read pre-images.

PreimageWrite

Write-only. Used to request pre-images.

Wildcard(usize)

Other file descriptor.

Trait Implementations

impl Clone for FileDescriptor

fn clone(&self) -> FileDescriptor

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FileDescriptor

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

Formats the value using the given formatter.

impl From<FileDescriptor> for i32

fn from(fd: FileDescriptor) -> Self

Converts to this type from the input type.

impl From<FileDescriptor> for usize

fn from(fd: FileDescriptor) -> Self

Converts to this type from the input type.

impl PartialEq for FileDescriptor

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