Struct Parser 

pub struct Parser;

Parser for YAML documents.

Wraps saphyr’s YAML loading to provide a consistent API.

Implementations

impl Parser

pub fn parse_str(input: &str) -> ParseResult<Option<Value>>

Parse a single YAML document from a string.

Returns the first document if multiple are present, or None if the input is empty.

Errors

Returns ParseError::Scanner if the YAML syntax is invalid.

Examples

use fast_yaml_core::Parser;

let result = Parser::parse_str("name: test\nvalue: 123")?;

pub fn parse_all(input: &str) -> ParseResult<Vec<Value>>

Parse all YAML documents from a string.

Returns a vector of all documents found in the input.

Errors

Returns ParseError::Scanner if the YAML syntax is invalid.

Examples

use fast_yaml_core::Parser;

let docs = Parser::parse_all("---\nfoo: 1\n---\nbar: 2")?;
assert_eq!(docs.len(), 2);

pub fn parse_all_preserving_styles(input: &str) -> ParseResult<Vec<Value>>

Parse all YAML documents preserving scalar styles (literal |, folded >).

Unlike parse_all, this function uses early_parse = false in the loader, which keeps scalars as Value::Representation nodes with their original style information instead of resolving them eagerly.

This is used by the format pipeline to preserve block scalar styles in output.

Errors

Returns ParseError::Scanner if the YAML syntax is invalid.
