pub struct FdTable {
    pub fds: BTreeMap<i32, FileDescriptionRef>,
    next_file_description_id: FdId,
}

The file descriptor table

Fields

fds: BTreeMap<i32, FileDescriptionRef>

next_file_description_id: FdId

Unique identifier for file description, used to differentiate between various file description.

Implementations

impl FdTable

fn new() -> Self

pub(crate) fn init(mute_stdout_stderr: bool) -> FdTable

pub fn new_ref(&mut self, fd: impl FileDescription) -> FileDescriptionRef

pub fn insert_new(&mut self, fd: impl FileDescription) -> i32

Insert a new file description to the FdTable.

pub fn insert(&mut self, fd_ref: FileDescriptionRef) -> i32

fn insert_ref_with_min_fd( &mut self, file_handle: FileDescriptionRef, min_fd: i32, ) -> i32

Insert a file description, giving it a file descriptor that is at least min_fd.

pub fn get(&self, fd: i32) -> Option<FileDescriptionRef>

pub fn remove(&mut self, fd: i32) -> Option<FileDescriptionRef>

pub fn is_fd(&self, fd: i32) -> bool

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
