Struct M 

pub struct M<'a>(pub Upgrade<'a>, pub Option<Downgrade<'a>>);

Single migration M with Upgrade and optional Downgrade

Tuple Fields

0: Upgrade<'a>

1: Option<Downgrade<'a>>

Implementations

impl M<'_>

pub fn as_tuple(&self) -> (&'_ Upgrade<'_>, Option<&'_ Downgrade<'_>>)

Use tuple struct as tuple

Trait Implementations

impl<'a> Clone for M<'a>

fn clone(&self) -> M<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for M<'a>

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

Formats the value using the given formatter.

impl<'a> Eq for M<'a>

impl<'a> From<&'a M<'a>> for (&'a Upgrade<'a>, Option<&'a Downgrade<'a>>)

fn from(value: &'a M<'a>) -> Self

Converts to this type from the input type.

impl<'a> From<&'a M<'a>> for Migration<'a, Request<Post>>

Available on crate feature ureq only.

Create Migration from single M reference

fn from(value: &'a M<'a>) -> Self

Converts to this type from the input type.

impl<'a> From<M<'a>> for Migration<'a, Request<Post>>

Available on crate feature ureq only.

Create Migration from single M

fn from(value: M<'a>) -> Self

Converts to this type from the input type.

impl<'a> PartialEq for M<'a>

fn eq(&self, other: &M<'a>) -> 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.
