Struct WriteCtx 

#[non_exhaustive]
pub struct WriteCtx<'a, E> {
    pub kind: WriteKind,
    pub before: Option<&'a E>,
    pub after: Option<&'a E>,
    pub actor: Option<String>,
    pub at: DateTime<Utc>,
}

One write, as the guard sees it.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

kind: WriteKind

before: Option<&'a E>

The row as stored before the write; None on create.

after: Option<&'a E>

The row the write would store; None on delete and hard delete.

actor: Option<String>

Who is writing: the request’s audit attribution, when the composing service bound one; None for a job, a seed or an unscoped caller.

at: DateTime<Utc>

When the write happens, the now() a rule compares against.

Implementations

impl<'a, E> WriteCtx<'a, E>

pub fn new(kind: WriteKind, before: Option<&'a E>, after: Option<&'a E>) -> Self

The context of one write, attributed to the ambient request’s actor and timed now.

Trait Implementations

impl<'a, E: Debug> Debug for WriteCtx<'a, E>

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

Formats the value using the given formatter.
