Struct FormValidationManager 

pub struct FormValidationManager { /* private fields */ }

The outcome of the last constraint validation, so a callback can ask why its control was rejected.

Replaced WHOLESALE on each validation rather than merged, which is what makes a control that has since been fixed stop reporting: it simply is not in the new map.

Implementations

impl FormValidationManager

pub fn new() -> Self

pub fn set_failures( &mut self, failures: impl IntoIterator<Item = (DomNodeId, ValidityState)>, )

Publish the result of one validation pass.

pub fn state_of(&self, node: DomNodeId) -> ValidityState

Why this control failed, or ValidityState::valid if it did not.

A control nothing has validated yet reads as VALID rather than as unknown. That is the honest answer for a form nobody has submitted - HTML says the same, since an untouched field is valid until a constraint check says otherwise.

pub fn failing_nodes(&self) -> Vec<DomNodeId>

Every control that failed the last validation, in document order.
