Version requirement syntax accepted by the CLI crates.io resolver.

Implementations

impl VersionReq

pub fn matches(&self, version: &str) -> bool

Reports whether a concrete version satisfies this requirement.

Examples

use sim_run_core::VersionReq;

let caret: VersionReq = "^0.1".parse().unwrap();
assert!(caret.matches("0.1.9"));
assert!(!caret.matches("0.2.0"));

pub fn as_str(&self) -> &str

Returns the original requirement text.

impl Eq for VersionReq

impl FromStr for VersionReq

type Err = CliError

The associated error which can be returned from parsing.

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

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

impl PartialEq for VersionReq

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