Struct TftpMessage 

#[non_exhaustive]
pub struct TftpMessage {
    pub opcode: TftpOpcode,
    pub filename: Option<String>,
    pub mode: Option<TftpMode>,
    pub block: Option<u16>,
    pub data_len: Option<usize>,
    pub error_code: Option<TftpErrorCode>,
    pub error_message: Option<String>,
}

Available on crate feature tftp only.

One parsed TFTP packet. Field semantics depend on TftpMessage::opcode.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

opcode: TftpOpcode

The 2-byte opcode at the start of every TFTP packet.

filename: Option<String>

RRQ / WRQ: requested file name. Always None for the other opcodes.

mode: Option<TftpMode>

RRQ / WRQ: transfer mode (netascii / octet / mail). Always None for the other opcodes.

block: Option<u16>

DATA / ACK: block number (1-based).

data_len: Option<usize>

DATA: payload byte length. We don’t surface the bytes (too large), just the size — useful for transfer-volume counting.

error_code: Option<TftpErrorCode>

ERROR: error code (RFC 1350 §5).

error_message: Option<String>

ERROR: human-readable message.

Implementations

impl TftpMessage

pub fn is_device_config_transfer(&self) -> bool

true when this is a read or write request for a device-config-shaped filename — heuristic match for the strings Cisco / Juniper / Arista boxes use: running-config, startup-config, confg, .cfg suffix, .conf suffix. Operationally a useful config-theft IOC.
