Struct serde_yml::loader::Loader

pub struct Loader<'input> {
    pub parser: Option<Parser<'input>>,
    pub parsed_document_count: usize,
}

Represents a YAML loader.

Fields

parser: Option<Parser<'input>>

The YAML parser used to parse the input.

The Parser type is defined in the libyml module and represents a low-level YAML parser.

The 'input lifetime parameter indicates the lifetime of the input data being parsed. It ensures that the Loader does not outlive the input data.

parsed_document_count: usize

The count of documents parsed by the loader.

This field keeps track of the number of YAML documents encountered during parsing.

Implementations

impl<'input> Loader<'input>

pub fn new(progress: Progress<'input>) -> Result<Self>

Constructs a new Loader instance from the given progress.

Arguments

• progress - The progress representing the YAML input.

Errors

Returns an error if there is an issue reading the input.

Examples

use serde_yml::loader::Loader;
use serde_yml::de::Progress;

let input = "---\nkey: value";
let progress = Progress::Str(input);
let loader_result = Loader::new(progress);

assert!(loader_result.is_ok());

pub fn next_document(&mut self) -> Option<Document<'input>>

Advances the loader to the next document and returns it.

Returns

Returns Some(Document) if a document is successfully parsed, or None if there are no more documents.

Examples

use serde_yml::loader::{Loader, Document};
use serde_yml::de::Progress;

let input = "---\nkey: value";
let progress = Progress::Str(input);
let mut loader = Loader::new(progress).unwrap();
let document = loader.next_document().unwrap();

assert_eq!(document.events.len(), 4);
