BorrowedFileDescriptor

struct BorrowedFileDescriptor[origin: ImmOrigin]

Copyable, non-owning view of a FileDescriptor.

The view carries the owner's origin, so it cannot outlive the owner, and it never closes the descriptor. -1 is the niche, so Optional[BorrowedFileDescriptor] is the size of a descriptor.

Examples:

from std.io import BorrowedFileDescriptor, FileDescriptor

def share(var fd: FileDescriptor) raises:
    var first = BorrowedFileDescriptor(fd)
    var second = first
    fd^.close()

Parameters​

  • ​origin (ImmOrigin): The origin of the FileDescriptor this view refers to.

Implemented traits​

AnyType, Copyable, Deinitable, ImplicitlyCopyable, Movable, RegisterPassable, TrivialRegisterPassable, UnsafeNicheable, _FieldNicheable

Methods​
