Implementations

impl EnvOption

pub fn resolve_value(
    &self,
    config_parent: impl AsRef<Path>
) -> Result<Cow<'_, str>, EnvError>

Retrieve the value and canonicalize it relative to config_parent when EnvOption::Value::relative is set.

config_parent is the directory containing .cargo/config.toml where this was parsed from.

Trait Implementations

impl Clone for EnvOption

fn clone(&self) -> EnvOption

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EnvOption

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EnvOption

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq<EnvOption> for EnvOption

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

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

const 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.
