Enum cargo_update::ops::PackageFilterElement

pub enum PackageFilterElement {
    Toolchain(String),
}

One of elements with which to filter required packages.

Variants

Toolchain(String)

Requires toolchain to be specified to the specified toolchain.

Parsed name: "toolchain".

Methods

impl PackageFilterElement

pub fn parse(from: &str) -> Result<PackageFilterElement, String>

Parse one filter specifier into up to one package filter

Examples

assert_eq!(PackageFilterElement::parse("toolchain=nightly"),
           Ok(PackageFilterElement::Toolchain("nightly".to_string())));

assert!(PackageFilterElement::parse("capitalism").is_err());
assert!(PackageFilterElement::parse("communism=good").is_err());

pub fn matches(&self, cfg: &PackageConfig) -> bool

Check if the specified package config matches this filter element.

Examples

assert!(PackageFilterElement::Toolchain("nightly".to_string())
    .matches(&PackageConfig::from(&[ConfigOperation::SetToolchain("nightly".to_string())])));

assert!(!PackageFilterElement::Toolchain("nightly".to_string()).matches(&PackageConfig::from(&[])));
