Struct yamlpath::Document

pub struct Document { /* private fields */ }

Represents a queryable YAML document.

Implementations

impl Document

pub fn new(source: impl Into<String>) -> Result<Self, QueryError>

Construct a new Document from the given YAML.

pub fn root(&self) -> Feature<'_>

Returns a Feature for this document’s root node.

This is typically useful as a “fallback” feature, e.g. for capturing a span of the entire document.

pub fn query(&self, query: &Query) -> Result<Feature<'_>, QueryError>

Perform a query on the current document, returning a Feature if the query succeeds.

pub fn extract(&self, feature: &Feature<'_>) -> &str

Returns a slice of the original document corresponding to the given Feature.

Panics if the feature’s span is invalid.

pub fn line_comment(&self, feature: &Feature<'_>) -> Option<&str>

Given a Feature, return the comment (if one exists) on the first line of the feature’s location.

This is not a fully general comment extraction API: it only extracts comments on matching lines.
