Trait Implementations

impl Clone for UnixFs

fn clone(&self) -> UnixFs

Returns a duplicate of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for UnixFs

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

Formats the value using the given formatter.

impl Decoder<UnixFs> for Ipld

fn decode(&self) -> Result<UnixFs, CarError>

impl Default for UnixFs

fn default() -> UnixFs

Returns the “default value” for a type.

impl Encoder<Ipld> for UnixFs

fn encode(&self) -> Result<Ipld, CarError>

impl PartialEq for UnixFs

fn eq(&self, other: &UnixFs) -> bool

Tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<(Cid<64>, Ipld)> for UnixFs

type Error = CarError

The type returned in the event of a conversion error.

fn try_from(value: (Cid, Ipld)) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Ipld> for UnixFs

type Error = CarError

The type returned in the event of a conversion error.

fn try_from(value: Ipld) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<UnixFs> for Ipld

type Error = CarError

The type returned in the event of a conversion error.

fn try_from(value: UnixFs) -> Result<Self, Self::Error>

Performs the conversion.
