Struct Directive 

pub struct Directive(/* private fields */);

A YAML directive like %YAML 1.2

Note: This type uses interior mutability through the rowan library. Mutation methods work even when called through &self. See the crate-level documentation for details on the mutability model.

Implementations

impl Directive

pub fn text(&self) -> String

Get the full directive text (e.g., “%YAML 1.2”)

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

Get the directive name (e.g., “YAML” from “%YAML 1.2”)

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

Get the directive value (e.g., “1.2” from “%YAML 1.2”)

pub fn is_yaml_version(&self) -> bool

Check if this is a YAML version directive

pub fn is_tag(&self) -> bool

Check if this is a TAG directive

pub fn new_yaml_version(version: &str) -> Self

Create a new YAML version directive

pub fn new_tag(handle: &str, prefix: &str) -> Self

Create a new TAG directive

impl Clone for Directive

fn clone(&self) -> Directive

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Directive

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

Formats the value using the given formatter.

impl Display for Directive

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

Formats the value using the given formatter.

impl Hash for Directive

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,

impl PartialEq for Directive

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