Struct Refusal 

pub struct Refusal {
    pub column: Option<String>,
    pub reason: String,
}

A refusal: a change the planner will not perform, with a human-readable reason. A plan with any refusal must fail loud — never silently degrade.

Fields

column: Option<String>

The column the refusal concerns (or the table, when None).

reason: String

Why the change was refused.

Trait Implementations

impl Clone for Refusal

fn clone(&self) -> Refusal

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Refusal

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

Formats the value using the given formatter.

impl PartialEq for Refusal

fn eq(&self, other: &Refusal) -> 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.
