Serde-based serialization format for anonymous “value” types.

Variants

Variable(Variable<Format>)

A format whose value is initially unknown. Used internally for tracing. Not (de)serializable.

TypeName(String)

The name of a container.

Unit

Bool

I8

I16

I32

I64

I128

U8

U16

U32

U64

U128

F32

F64

Char

Str

Bytes

Option(Box<Format>)

The format of Option<T>.

Seq(Box<Format>)

A sequence, e.g. the format of Vec<Foo>.

Map

A map, e.g. the format of BTreeMap<K, V>.

Fields

key: Box<Format>

value: Box<Format>

Tuple(Vec<Format>)

A tuple, e.g. the format of (Foo, Bar).

TupleArray

Alias for (Foo, ... Foo). E.g. the format of [Foo; N].

Fields

content: Box<Format>

size: usize

Implementations

impl Format

pub fn unknown() -> Self

Return a format made of a fresh variable with no known value.

Trait Implementations

impl Clone for Format

fn clone(&self) -> Format

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Format

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

Formats the value using the given formatter.

impl Default for Format

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Format

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FormatHolder for Format

fn unify(&mut self, format: Format) -> Result<()>

Unify the newly “traced” value format into the current format. Note that there should be no TupleArrays at this point.

fn visit<'a>( &'a self, f: &mut dyn FnMut(&'a Format) -> Result<()>, ) -> Result<()>

Visit all the formats in self in a depth-first way. Variables are not supported and will cause an error.

fn visit_mut( &mut self, f: &mut dyn FnMut(&mut Format) -> Result<()>, ) -> Result<()>

Mutably visit all the formats in self in a depth-first way.

fn is_unknown(&self) -> bool

Whether this format is a variable with no known value yet.

fn normalize(&mut self) -> Result<()>

Finalize the formats within self by removing variables and making sure that all eligible tuples are compressed into a TupleArray. Return an error if any variable has an unknown value.

fn reduce(&mut self)

Attempt to remove known variables within self. Silently abort if some variables have unknown values.

impl PartialEq for Format

fn eq(&self, other: &Format) -> 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 Serialize for Format

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Format

impl StructuralPartialEq for Format
