Implementations

impl FrameKind

pub fn is_aggregate_type(&self) -> bool

Whether the frame is an aggregate type (array, set, map).

pub fn is_streaming_type(&self) -> bool

Whether the frame is an aggregate type or blob string.

pub fn can_hash(&self) -> bool

Whether the frame can be used as a key in a HashMap or HashSet.

Not all frame types can be hashed, and trying to do so can panic. This function can be used to handle this gracefully.

pub fn hash_prefix(&self) -> &'static str

A function used to differentiate data types that may have the same inner binary representation when hashing.

pub fn from_byte(d: u8) -> Option<FrameKind>

Attempt to detect the type of the frame from the first byte.

pub fn to_byte(&self) -> u8

Read the byte prefix for the associated frame type.

Trait Implementations

impl Clone for FrameKind

fn clone(&self) -> FrameKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FrameKind

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

Formats the value using the given formatter.

impl Hash for FrameKind

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 Ord for FrameKind

fn cmp(&self, other: &FrameKind) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for FrameKind

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for FrameKind

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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