Struct confql_data_resolver::DataPath

pub struct DataPath<'a> { /* fields omitted */ }

Represents a position in the data directory when resolving data.

Implementations

impl<'a> DataPath<'a>

pub fn descend(self) -> Option<Self>

Takes self by value, and steps to the next logical data path (mutating self). Returns None if there’s nowhere to go.

pub fn done(&self) -> bool

Returns whether or not this instance is exhausted, i.e. when descend would be a no-op

pub fn file_stem(&self) -> Option<&OsStr>

Returns the current path file stem (i.e. basename without file extension)

pub fn join<P: AsRef<Path>>(&self, tail: P) -> Self

Spawns a new instance with a given path suffix appended, and same data address.

pub fn new<P: Into<PathBuf>>(path: P, address: &'a [&'a str]) -> Self

Creates a new instance from a path and data address.

pub fn sub_paths(&self) -> Vec<Self>

Creates a vector of new instances, one for each file/directory at the current path.

pub fn value(&self) -> Result<Value, DataResolverError>

Tries to convert the current position to a serde_yaml::Value.
