#[non_exhaustive]
pub enum Op { Exact, Greater, GreaterEq, Less, LessEq, Tilde, Caret, Wildcard, }
Expand description

SemVer comparison operator: =, >, >=, <, <=, ~, ^, *.

§Op::Exact

  • =I.J.K — exactly the version I.J.K
  • =I.J — equivalent to >=I.J.0, <I.(J+1).0
  • =I — equivalent to >=I.0.0, <(I+1).0.0

§Op::Greater

  • >I.J.K
  • >I.J — equivalent to >=I.(J+1).0
  • >I — equivalent to >=(I+1).0.0

§Op::GreaterEq

  • >=I.J.K
  • >=I.J — equivalent to >=I.J.0
  • >=I — equivalent to >=I.0.0

§Op::Less

  • <I.J.K
  • <I.J — equivalent to <I.J.0
  • <I — equivalent to <I.0.0

§Op::LessEq

  • <=I.J.K
  • <=I.J — equivalent to <I.(J+1).0
  • <=I — equivalent to <(I+1).0.0

§Op::Tilde (“patch” updates)

Tilde requirements allow the patch part of the semver version (the third number) to increase.

  • ~I.J.K — equivalent to >=I.J.K, <I.(J+1).0
  • ~I.J — equivalent to =I.J
  • ~I — equivalent to =I

§Op::Caret (“compatible” updates)

Caret requirements allow parts that are right of the first nonzero part of the semver version to increase.

  • ^I.J.K (for I>0) — equivalent to >=I.J.K, <(I+1).0.0
  • ^0.J.K (for J>0) — equivalent to >=0.J.K, <0.(J+1).0
  • ^0.0.K — equivalent to =0.0.K
  • ^I.J (for I>0 or J>0) — equivalent to ^I.J.0
  • ^0.0 — equivalent to =0.0
  • ^I — equivalent to =I

§Op::Wildcard

  • I.J.* — equivalent to =I.J
  • I.* or I.*.* — equivalent to =I

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
