Enum Opcode 

#[repr(u16)]
pub enum Opcode {
    Rrq = 1,
    Wrq = 2,
    Data = 3,
    Ack = 4,
    Error = 5,
    Oack = 6,
}

Opcode enum represents the opcodes used in the TFTP definition.

This enum has function implementations for converting u16s to Opcodes and Opcodes to u8 arrays.

Example

use tftpd::Opcode;

assert_eq!(Opcode::from_u16(3).unwrap(), Opcode::Data);
assert_eq!(Opcode::Ack.as_bytes(), [0x00, 0x04]);

Variants

Rrq = 1

Read request opcode

Wrq = 2

Write request opcode

Data = 3

Data opcode

Ack = 4

Acknowledgement opcode

Error = 5

Error opcode

Oack = 6

Option acknowledgement opcode

Implementations

impl Opcode

pub fn from_u16(val: u16) -> Result<Opcode, &'static str>

Converts a u16 to an Opcode.

pub const fn as_bytes(self) -> [u8; 2]

Converts a u16 to a u8 array with 2 elements.

Trait Implementations

impl Debug for Opcode

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

Formats the value using the given formatter.

impl PartialEq for Opcode

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