Struct piston_meta_search::Search

pub struct Search<'a> {
    pub range: Option<Range>,
    pub data: &'a [Range<MetaData>],
}

Used to search through meta data.

Fields

range: Option<Range>

The previous range of search. Used in errors if there is no meta data left.

data: &'a [Range<MetaData>]

The data to search.

Implementations

impl<'a> Search<'a>

pub fn new(data: &'a [Range<MetaData>]) -> Search<'a>

Creates a new search.

pub fn for_string<T, F>(
    &'a self,
    name: &str,
    val: &str,
    f: F
) -> Result<T, Range<ParseError>> where
    F: FnOnce(Search<'a>) -> Result<T, Range<ParseError>>, 

Searches anywhere in meta data for a string. Calls closure on the first match.

pub fn for_f64<T, F>(
    &'a self,
    name: &str,
    val: f64,
    f: F
) -> Result<T, Range<ParseError>> where
    F: FnOnce(Search<'a>) -> Result<T, Range<ParseError>>, 

Searches anywhere in meta data for a f64. Calls closure on the first match.

pub fn for_bool<T, F>(
    &'a self,
    name: &str,
    val: bool,
    f: F
) -> Result<T, Range<ParseError>> where
    F: FnOnce(Search<'a>) -> Result<T, Range<ParseError>>, 

Searches anywhere in meta data for a bool. Calls closure on the first match.

pub fn for_node<T, F>(
    &'a self,
    name: &str,
    f: F
) -> Result<T, Range<ParseError>> where
    F: FnOnce(Search<'a>) -> Result<T, Range<ParseError>>, 

Searches anywhere in meta data for a node. Calls closure on the first match.

pub fn for_end_node<T, F>(
    &'a self,
    name: &str,
    f: F
) -> Result<T, Range<ParseError>> where
    F: FnOnce(Search<'a>) -> Result<T, Range<ParseError>>, 

Searches anywhere in meta data for an end node. Calls closure on the first match.

pub fn bool(&mut self, name: &str) -> Result<bool, Range<ParseError>>

Reads next as bool value.

pub fn f64(&mut self, name: &str) -> Result<f64, Range<ParseError>>

Reads next as f64 value.

pub fn string(&mut self, name: &str) -> Result<Arc<String>, Range<ParseError>>

Reads next as string value.

pub fn node(&mut self, name: &str) -> Result<(), Range<ParseError>>

Reads next as node.

pub fn end_node(&mut self, name: &str) -> Result<(), Range<ParseError>>

Reads next as end node.
