Struct CfgPath 

pub struct CfgPath(/* private fields */);

A path in a configuration file: tilde expansion is performed, along with expansion of variables provided by a CfgPathResolver.

The tilde expansion is performed using the home directory given by the directories crate, which may be based on an environment variable. For more information, see BaseDirs::home_dir.

Alternatively, a CfgPath can contain literal PathBuf, which will not be expanded.

Implementations

impl CfgPath

pub fn new(s: String) -> Self

Create a new configuration path

pub fn new_literal<P: Into<PathBuf>>(path: P) -> Self

Construct a new CfgPath designating a literal not-to-be-expanded PathBuf

pub fn path( &self, path_resolver: &CfgPathResolver, ) -> Result<PathBuf, CfgPathError>

Return the path on disk designated by this CfgPath.

Variables may or may not be resolved using path_resolver, depending on whether the expand-paths feature is enabled or not.

pub fn as_unexpanded_str(&self) -> Option<&str>

If the CfgPath is a string that should be expanded, return the (unexpanded) string,

Before use, this string would have be to expanded. So if you want a path to actually use, call path instead.

Returns None if the CfgPath is a literal PathBuf not intended for expansion.

pub fn as_literal_path(&self) -> Option<&Path>

If the CfgPath designates a literal not-to-be-expanded Path, return a reference to it

Returns None if the CfgPath is a string which should be expanded, which is the usual case.

Trait Implementations

impl Clone for CfgPath

fn clone(&self) -> CfgPath

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CfgPath

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CfgPath

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for CfgPath

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for CfgPath

fn eq(&self, other: &CfgPath) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for CfgPath

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for CfgPath

impl StructuralPartialEq for CfgPath

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
