Enum DefaultVersioning 

pub enum DefaultVersioning {
    Inferred,
    Timestamp,
    Sequential,
}

Available on crate feature _unstable-docs only.

The default scheme that sqlx migrate add should use for version integers.

Variants

Inferred

Infer the versioning scheme from existing migrations:

• If the versions of the last two migrations differ by 1, infer Sequential.
• If only one migration exists and has version 1, infer Sequential.
• Otherwise, infer Timestamp.

Timestamp

Use UTC timestamps for migration versions.

This is the recommended versioning format as it’s less likely to collide when multiple developers are creating migrations on different branches.

The exact timestamp format is unspecified.

Sequential

Use sequential integers for migration versions.

Trait Implementations

impl Debug for DefaultVersioning

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for DefaultVersioning

fn default() -> DefaultVersioning

Returns the “default value” for a type.

impl PartialEq for DefaultVersioning

fn eq(&self, other: &DefaultVersioning) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
