Struct dia_semver::Semver

pub struct Semver {
    pub major: u64,
    pub minor: u64,
    pub patch: u64,
    pub pre_release: Option<String>,
    pub build_metadata: Option<String>,
}

Semver.

Some concepts

• Strict parser does not allow leading/trailing while spaces; all 3 version numbers are required: major, minor, patch.
• Tolerant parser ignores leading/trailing while spaces. Minor and patch version numbers are optional. This mode is added by the crate author, it's not described in official specification.

Usage

• ::parse*() methods use strict parser. While ::new() and ::from_*() ones are more tolerant.

Fields

major: u64

Major.

minor: u64

Minor.

patch: u64

Patch.

pre_release: Option<String>

Pre-release.

build_metadata: Option<String>

Build metadata.

Methods

impl Semver

pub fn parse(s: &str, strict: bool) -> Result<Semver, ParseSemverError>

Parses input string to make a new semver.

Rules:

• If strict is true, minor and patch version numbers are required. Leading/trailing while spaces are not allowed.
• If strict is false, minor and patch version numbers are optional. Leading/trailing while spaces are ignored.

Examples

use dia_semver::Semver;

assert_eq!(Semver::parse("1.2.3", true).unwrap().to_string(), "1.2.3");
assert_eq!(Semver::parse("          1-a.b.c           ", false).unwrap().to_string(), "1.0.0-a.b.c");

pub fn new(s: &str) -> Result<Semver, ParseSemverError>

Parses a &str.

This method calls ::parse() with false passed to strict.

pub fn parse_os_str(s: &OsStr, strict: bool) -> Result<Semver, ParseSemverError>

Parses an &OsStr.

See ::parse() for details.

pub fn from_os_str(s: &OsStr) -> Result<Semver, ParseSemverError>

Parses an &OsStr.

This method calls ::parse_os_str() with false passed to strict.

pub fn parse_c_str(s: &CStr, strict: bool) -> Result<Semver, ParseSemverError>

Parses a &CStr.

See ::parse() for details.

pub fn from_c_str(s: &CStr) -> Result<Semver, ParseSemverError>

Parses a &CStr.

This method calls ::parse_c_str() with false passed to strict.
