Implementations

impl Group

pub fn new(fields: Vec<Box<dyn Field>>) -> Self

Creates a new group with the given fields.

pub fn title(self, title: impl Into<String>) -> Self

Sets the group title.

pub fn description(self, description: impl Into<String>) -> Self

Sets the group description.

pub fn hide(self, hide: bool) -> Self

Sets whether the group should be hidden.

pub fn hide_func<F: Fn() -> bool + Send + Sync + 'static>(self, f: F) -> Self

Sets a function to determine if the group should be hidden.

pub fn is_hidden(&self) -> bool

Returns whether this group should be hidden.

pub fn current(&self) -> usize

Returns the current field index.

pub fn len(&self) -> usize

Returns the number of fields.

pub fn is_empty(&self) -> bool

Returns whether the group has no fields.

pub fn current_field(&self) -> Option<&dyn Field>

Returns a reference to the current field.

pub fn current_field_mut(&mut self) -> Option<&mut Box<dyn Field>>

Returns a mutable reference to the current field.

pub fn errors(&self) -> Vec<&str>

Collects all field errors.

pub fn header(&self) -> String

Returns the header portion of the group (title and description).

This is useful for custom layouts that want to render the header separately from the content.

pub fn content(&self) -> String

Returns the content portion of the group (just the fields).

This is useful for custom layouts that want to render the content separately from the header and footer.

pub fn footer(&self) -> String

Returns the footer portion of the group (currently errors).

This is useful for custom layouts that want to render the footer separately from the content.
