Implementations

impl<W: Write> Encoder<W>

pub fn array(&mut self, len: usize) -> Result<(), W::Error>

Begin encoding an array with len elements.

pub fn begin_array(&mut self) -> Result<(), W::Error>

Begin encoding an array of unknown size.

Use Encoder::end to terminate the array.

pub fn map(&mut self, len: usize) -> Result<(), W::Error>

Begin encoding a map with len entries.

pub fn begin_map(&mut self) -> Result<(), W::Error>

Begin encoding a map of unknown size.

Use Encoder::end to terminate the map.

pub fn begin_bytes(&mut self) -> Result<(), W::Error>

Begin encoding an indefinite number of byte slices.

Use Encoder::end to terminate.

pub fn begin_str(&mut self) -> Result<(), W::Error>

Begin encoding an indefinite number of string slices.

Use Encoder::end to terminate.

pub fn end(&mut self) -> Result<(), W::Error>

Terminate an indefinite collection.

Trait Implementations

impl<W: Clone> Clone for Encoder<W>

fn clone(&self) -> Encoder<W>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<W: Debug> Debug for Encoder<W>

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

Formats the value using the given formatter.

impl<W: Default> Default for Encoder<W>

fn default() -> Encoder<W>

Returns the “default value” for a type.

impl<W: Hash> Hash for Encoder<W>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<W: Ord> Ord for Encoder<W>

fn cmp(&self, other: &Encoder<W>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<W: PartialEq> PartialEq for Encoder<W>

fn eq(&self, other: &Encoder<W>) -> 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.

impl<W: PartialOrd> PartialOrd for Encoder<W>

fn partial_cmp(&self, other: &Encoder<W>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
