Struct TreeConfig 

#[non_exhaustive]
pub struct TreeConfig {
    pub parent_key: String,
    pub source: Option<String>,
}

Rows that form a tree through a parent column (adjacency): the list opens on the rows with no parent, each row with children expands in place, and a row can be moved under another parent.

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.

parent_key: String

The column holding a row’s parent id, null at the top level. Default parent_id.

source: Option<String>

A registered picker source over this entity. When set, every row offers “Move to”, which picks the new parent from it; empty means the top level.

Implementations

impl TreeConfig

pub fn new(parent_key: impl Into<String>) -> Self

A tree on parent_key.

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

Offers “Move to” on every row, picking the new parent from source.
