Enum Yaml 

pub enum Yaml {
    Null,
    Bool(bool),
    Int(i64),
    Float(f64),
    Str(String),
    Seq(Vec<Yaml>),
    Map(Vec<(String, Yaml)>),
}

A parsed YAML-subset value.

Variants

Null

null, ~, or an empty value.

Bool(bool)

true / false.

Int(i64)

An integer.

Float(f64)

A floating-point number.

Str(String)

A string, quoted or bare.

Seq(Vec<Yaml>)

A block sequence.

Map(Vec<(String, Yaml)>)

A block mapping. Order is preserved so emitted files are stable.

Implementations

impl Yaml

pub fn get(&self, key: &str) -> Option<&Yaml>

Look up a key in a mapping.

pub fn as_str(&self) -> Option<&str>

Borrow as a string, accepting any scalar and rendering it.

pub fn as_string(&self) -> Option<String>

Read a string, or None for null/missing.

pub fn as_bool(&self) -> Option<bool>

Read a boolean.

pub fn as_f64(&self) -> Option<f64>

Read a number as f64, accepting integers.

pub fn as_u64(&self) -> Option<u64>

Read a number as u64.

pub fn as_seq(&self) -> Option<&[Yaml]>

Borrow as a sequence.

pub fn as_string_list(&self) -> Vec<String>

Read a sequence of strings, tolerating a missing or null value.

pub fn is_null(&self) -> bool

Whether the value is null.

Trait Implementations

impl Clone for Yaml

fn clone(&self) -> Yaml

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Yaml

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

Formats the value using the given formatter.

impl From<&str> for Yaml

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<String> for Yaml

fn from(value: String) -> Self

Converts to this type from the input type.

impl From<bool> for Yaml

fn from(value: bool) -> Self

Converts to this type from the input type.

impl From<f32> for Yaml

fn from(value: f32) -> Self

Converts to this type from the input type.

impl From<u32> for Yaml

fn from(value: u32) -> Self

Converts to this type from the input type.

impl From<u64> for Yaml

fn from(value: u64) -> Self

impl PartialEq for Yaml

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