Variants

StreamStart(TEncoding)

The start of the stream. Sent first, before even TokenType::DocumentStart.

StreamEnd

The end of the stream, EOF.

VersionDirective(u32, u32)

A YAML version directive.

Tuple Fields

0: u32

Major

1: u32

Minor

TagDirective(String, String)

A YAML tag directive (e.g.: !!str, !foo!bar, …).

Tuple Fields

0: String

Handle

1: String

Prefix

DocumentStart

The start of a YAML document (---).

DocumentEnd

The end of a YAML document (...).

BlockSequenceStart

The start of a sequence block.

Sequence blocks are arrays starting with a -.

BlockMappingStart

The start of a sequence mapping.

Sequence mappings are “dictionaries” with “key: value” entries.

BlockEnd

End of the corresponding BlockSequenceStart or BlockMappingStart.

FlowSequenceStart

Start of an inline array ([ a, b ]).

FlowSequenceEnd

End of an inline array.

FlowMappingStart

Start of an inline mapping ({ a: b, c: d }).

FlowMappingEnd

End of an inline mapping.

BlockEntry

An entry in a block sequence (c.f.: TokenType::BlockSequenceStart).

FlowEntry

An entry in a flow sequence (c.f.: TokenType::FlowSequenceStart).

Key

A key in a mapping.

Value

A value in a mapping.

Alias(String)

A reference to an anchor.

Anchor(String)

A YAML anchor (&/*).

Tag(String, String)

A YAML tag (starting with bangs !).

Tuple Fields

0: String

The handle of the tag.

1: String

The suffix of the tag.

Scalar(TScalarStyle, String)

A regular YAML scalar.

Trait Implementations

impl Clone for TokenType

fn clone(&self) -> TokenType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TokenType

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

Formats the value using the given formatter.

impl PartialEq for TokenType

fn eq(&self, other: &TokenType) -> 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 Eq for TokenType

impl StructuralPartialEq for TokenType
