Struct TreeColumnSet 

pub struct TreeColumnSet<'a, T: TreeModel> { /* private fields */ }

A dynamic column set parsed and validated once at construction.

Implementations

impl<'a, T: TreeModel> TreeColumnSet<'a, T>

pub fn new( columns: impl IntoIterator<Item = ColumnDef<'a, T>>, ) -> Result<Self, TreeColumnsError>

Validates the set and records its single tree column.

Errors

Returns TreeColumnsError when the set is empty or does not contain exactly one tree column.

pub const fn header_style(self, style: Style) -> Self

Sets the header style.

pub const fn without_header(self) -> Self

Hides the header.
