Struct MigrationId

pub struct MigrationId(/* private fields */);

A migration ID

This is an integer referring to a row of an MigrationTable.

The features for this type follow the same pattern as for NodeId

Implementations

impl MigrationId

pub const NULL: MigrationId

NULL value for this type.

pub fn is_null(&self) -> bool

Return true is self == Self::NULL

pub fn to_usize(&self) -> Option<usize>

Convenience function to convert to usize.

Works via TryFrom.

Returns

• None if the underlying value is negative.
• Some(usize) otherwise.

pub fn as_usize(&self) -> usize

Convenience function to convert to usize. Implemented via as. Negative values with therefore wrap.
