Enum RequestedVersion 

pub enum RequestedVersion {
    Path(PathBuf),
    SystemDefault,
    Requirement(VersionReq),
    NoValue,
}

Variants

Path(PathBuf)

A specific path to the clang tool binary.

SystemDefault

Whatever the system default uses (if any).

Requirement(VersionReq)

A specific version requirement for the clang tool binary.

For example, =12.0.1, >=10.0.0, <13.0.0.

NoValue

A sentinel when no value is given.

This is used internally to differentiate when the user intended to invoke the version subcommand instead.

Trait Implementations

impl Clone for RequestedVersion

fn clone(&self) -> RequestedVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RequestedVersion

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

Formats the value using the given formatter.

impl Default for RequestedVersion

fn default() -> RequestedVersion

Returns the “default value” for a type.

impl FromStr for RequestedVersion

type Err = Error

The associated error which can be returned from parsing.

fn from_str(input: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for RequestedVersion

fn eq(&self, other: &RequestedVersion) -> 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.
