Struct MigrationVersion 

pub struct MigrationVersion {
    pub segments: Vec<u64>,
    pub raw: String,
}

A parsed migration version, supporting dotted numeric segments (e.g., “1.2.3”).

Equality

Two versions are equal when their numeric segments are equal after trailing zeros are dropped: 1, 1.0 and 1.0.0 are all the same version. The raw string is not part of the identity.

This has to match Ord, which compares zero-padded segment-wise. A derived PartialEq would compare raw too, so 1 and 1.0 would report Ordering::Equal from cmp while == said false — a violation of the Ord/Eq contract that silently corrupts BTreeMap, binary_search and dedup.

Fields

segments: Vec<u64>

Parsed numeric segments of the version (e.g., [1, 2, 3] for "1.2.3").

raw: String

Original version string as it appeared in the filename.

Implementations

impl MigrationVersion

pub fn normalized(&self) -> &[u64]

The segments with trailing zeros removed — the canonical identity used by PartialEq, Ord and std::hash::Hash.

1.0.0 normalizes to [1], 1.2.0 to [1, 2], and 0 / 0.0 to the empty slice (all-zero versions are equal to each other).

pub fn parse(raw: &str) -> Result<Self>

Parse a version string like "1.2.3" or "1_2" into segments.
