Trait ssh_encoding::Decode

pub trait Decode: Sized {
    type Error: From<Error>;

    // Required method
    fn decode(reader: &mut impl Reader) -> Result<Self, Self::Error>;
}

Decoding trait.

This trait describes how to decode a given type.

Required Associated Types

type Error: From<Error>

Type returned in the event of a decoding error.

Required Methods

fn decode(reader: &mut impl Reader) -> Result<Self, Self::Error>

Attempt to decode a value of this type using the provided Reader.

Implementations on Foreign Types

impl Decode for usize

Decode a usize.

Uses Decode impl on u32 and then converts to a usize, handling potential overflow if usize is smaller than u32.

Enforces a library-internal limit of 1048575, as the main use case for usize is length prefixes.

type Error = Error

fn decode(reader: &mut impl Reader) -> Result<Self>

impl Decode for u8

Decode a single byte from the input data.

type Error = Error

fn decode(reader: &mut impl Reader) -> Result<Self>

impl Decode for Vec<String>

Available on crate feature alloc only.

type Error = Error

fn decode(reader: &mut impl Reader) -> Result<Self>

impl Decode for u64

Decode a uint64 as described in RFC4251 § 5:

Represents a 64-bit unsigned integer. Stored as eight bytes in the order of decreasing significance (network byte order).

type Error = Error

fn decode(reader: &mut impl Reader) -> Result<Self>

impl<const N: usize> Decode for [u8; N]

Decodes a byte array from byte[n] as described in RFC4251 § 5:

A byte represents an arbitrary 8-bit value (octet). Fixed length data is sometimes represented as an array of bytes, written byte[n], where n is the number of bytes in the array.

type Error = Error

fn decode(reader: &mut impl Reader) -> Result<Self>

impl Decode for String

Available on crate feature alloc only.

type Error = Error

fn decode(reader: &mut impl Reader) -> Result<Self>

impl Decode for Vec<u8>

Available on crate feature alloc only.

Decodes Vec<u8> from byte[n] as described in RFC4251 § 5:

A byte represents an arbitrary 8-bit value (octet). Fixed length data is sometimes represented as an array of bytes, written byte[n], where n is the number of bytes in the array.

type Error = Error

fn decode(reader: &mut impl Reader) -> Result<Self>

impl Decode for Bytes

Available on crate feature bytes only.

Decodes Bytes from byte[n] as described in RFC4251 § 5:

A byte represents an arbitrary 8-bit value (octet). Fixed length data is sometimes represented as an array of bytes, written byte[n], where n is the number of bytes in the array.

type Error = Error

fn decode(reader: &mut impl Reader) -> Result<Self>

impl Decode for u32

Decode a uint32 as described in RFC4251 § 5:

Represents a 32-bit unsigned integer. Stored as four bytes in the order of decreasing significance (network byte order). For example: the value 699921578 (0x29b7f4aa) is stored as 29 b7 f4 aa.
