Function readSliceEndianAlloc [src]

The function is inline to avoid the dead code in case endian is comptime-known and matches host endianness.

Prototype

 pub inline fn readSliceEndianAlloc( r: *Reader, allocator: Allocator, comptime Elem: type, len: usize, endian: std.builtin.Endian, ) ReadAllocError![]Elem

Parameters

r: *Readerallocator: AllocatorElem: typelen: usizeendian: std.builtin.Endian

Possible Errors

EndOfStream Error

OutOfMemory Error

ReadFailed Error

See the Reader implementation for detailed diagnostics.
