example_parsing Crate

Examples for parsing values, mostly using nom.

example_parsing::semver

Exposes a SemanticVersion struct which is defined like this:

pub struct SemanticVersion {
    pub major: u64,
    pub minor: u64,
    pub bugfix: Option<u64>,
}

This type implements Display, FromStr, serde::Deserialize and serde::Serialize, and clap support is included and tested. The prefixed method will construct a semantic version string with a v prefix.

Values can be constructed using FromStr and from SemanticVersion::parse, as well as with all three components using SemanticVersion::new, or with only two components with SemanticVersion::abridged.

Parsing is done via nom, and should be extraordinarily fast.

String inputs should be of the forms:

• v1.2.3
• v0.1
• 1.2.3
• 0.1

String outputs will follow the same format yet will not be prefixed with a v unless SemanticVersion::prefixed is used.

Consult the module doc-strings for more information as well as the source code.
