Enum cargo::util::config::Definition

pub enum Definition {
    Path(PathBuf),
    Environment(String),
    Cli,
}

Location where a config value is defined.

Variants

Path(PathBuf)

Defined in a .cargo/config, includes the path to the file.

Environment(String)

Defined in an environment variable, includes the environment key.

Cli

Passed in on the command line.

Implementations

impl Definition

pub fn root<'a>(&'a self, config: &'a Config) -> &'a Path

Root directory where this is defined.

If from a file, it is the directory above .cargo/config. CLI and env are the current working directory.

pub fn is_higher_priority(&self, other: &Definition) -> bool

Returns true if self is a higher priority to other.

CLI is preferred over environment, which is preferred over files.

Trait Implementations

impl Clone for Definition

fn clone(&self) -> Definition

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Definition

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Definition

fn deserialize<D>(deserializer: D) -> Result<Definition, D::Error>where
    D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Definition

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

Formats the value using the given formatter.

impl PartialEq<Definition> for Definition

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Eq for Definition
