Enum FromSqlxError 

#[non_exhaustive]
pub enum FromSqlxError {
    NoTransaction {
        version: i64,
    },
    LedgerTable {
        table: String,
    },
    Setting(&'static str),
    Checksum {
        version: i64,
    },
}

Why an sqlx Migrator cannot be run by Migrates::migrate as it stands.

Each variant is something sqlx would honour and this crate would not: refusing is the point, so a program never believes it ran sqlx::migrate! and got a different run.

Variants (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.

NoTransaction

The migration asks to run outside a transaction (-- no-transaction, or no_tx on the Migrator); Migration always runs in one.

Fields

version: i64

The version.

LedgerTable

The Migrator keeps its ledger in another table than _sqlx_migrations, so this crate would read and write a different ledger than the program asked for.

Fields

table: String

The table the Migrator names.

Setting(&'static str)

The Migrator was set to create a schema or to skip locking; this crate always locks and never creates a schema.

Checksum

A migration’s stored checksum is not the SHA-384 of its text, so a ledger written by this crate would differ from the one sqlx writes for the same migration.

Fields

version: i64

The version.
