Enum TftpOpcode 

#[non_exhaustive]
pub enum TftpOpcode {
    ReadRequest,
    WriteRequest,
    Data,
    Ack,
    Error,
    Other(u16),
}

Available on crate feature tftp only.

TFTP opcode (RFC 1350 §5).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ReadRequest

1 — Read Request.

WriteRequest

2 — Write Request.

Data

3 — DATA block.

Ack

4 — DATA acknowledgement.

Error

5 — Error.

Other(u16)

Any other opcode value.
