Struct PathCache 

pub struct PathCache { /* private fields */ }

A cache of paths associated with names.

Implementations

impl PathCache

pub fn reset(&mut self)

Clears all elements from the cache.

pub fn get<S: AsRef<str>>(&self, name: S) -> Option<PathBuf>

Returns the path associated with the given name.

Arguments

• name - The name to lookup.

pub fn set<T: Into<String>>(&mut self, name: T, path: PathBuf)

Sets the path associated with the given name.

Arguments

• name - The name to set.
• path - The path to associate with the name.

pub fn to_value(&self) -> Result<ShellValue, Error>

Projects the cache into a shell value.

Errors

Returns any error from variables::ShellValue::associative_array_from_literals. Cache entries always carry keys, so this does not fail in practice.

pub fn unset<S: AsRef<str>>(&mut self, name: S) -> bool

Removes the path associated with the given name, if there is one. Returns whether or not an entry was removed.

Arguments

• name - The name to remove.
