Struct MigrationPlan

pub struct MigrationPlan {
    pub source_version: String,
    pub target_version: String,
    pub changes: Vec<SchemaChange>,
    pub impact_score: u8,
    pub is_breaking: bool,
}

Represents a plan for migrating between schema versions

A migration plan contains all the necessary changes required to evolve from one schema version to another, along with impact analysis.

Fields

source_version: String

Version of the source schema

target_version: String

Version of the target schema

changes: Vec<SchemaChange>

List of changes required for migration

impact_score: u8

Impact score (0-100) indicating the magnitude of changes

is_breaking: bool

Indicates whether this migration contains breaking changes

Implementations

impl MigrationPlan

pub fn new( source_version: String, target_version: String, changes: Vec<SchemaChange>, ) -> Self

Creates a new migration plan

Arguments

• source_version - Version identifier of the source schema
• target_version - Version identifier of the target schema
• changes - List of schema changes required for migration

Returns

A new MigrationPlan instance with calculated impact scores

pub fn breaking_changes(&self) -> Vec<&SchemaChange>

Gets a list of breaking changes in the migration plan

Returns

A vector of references to breaking changes
