Enum PlainScalarType 

pub enum PlainScalarType {
    Null,
    Bool(bool),
    Int(i64),
    Float(f64),
    Str,
    Value,
}

Result of resolving a plain (unquoted) scalar to a YAML type.

This is used by every composer variant to share implicit-resolution logic. Each composer maps the variants to its own value type.

Variants

Null

Null (null, Null, NULL, ~).

Bool(bool)

Boolean — under YAML 1.2 only true/false (any case); under YAML 1.1 also yes/no/on/off.

Int(i64)

64-bit signed integer (decimal).

Float(f64)

64-bit float.

Str

Falls through to a string — the caller keeps the original input.

Value

YAML 1.1 tag:yaml.org,2002:value (the bare = indicator, §10.3.4 of the 1.1 spec). Dropped from the 1.2 Core Schema, so the resolver only emits this under a %YAML 1.1 directive. Composers should reject it — there is no Value variant in the user-facing tree to construct it into. This mirrors ruamel.yaml typ="safe" / typ="unsafe", both of which raise ConstructorError.

Trait Implementations

impl Clone for PlainScalarType

fn clone(&self) -> PlainScalarType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PlainScalarType

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

Formats the value using the given formatter.

impl PartialEq for PlainScalarType

fn eq(&self, other: &PlainScalarType) -> 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.
