Trait NestedProgress

pub trait NestedProgress: Progress {
    type SubProgress: NestedProgress;

    // Required methods
    fn add_child(&mut self, name: impl Into<String>) -> Self::SubProgress;
    fn add_child_with_id(
        &mut self,
        name: impl Into<String>,
        id: [u8; 4],
    ) -> Self::SubProgress;
}

Available on crate feature progress only.

A trait for describing hierarchical progress.

Required Associated Types

type SubProgress: NestedProgress

The type of progress returned by [add_child()][Progress::add_child()].

Required Methods

fn add_child(&mut self, name: impl Into<String>) -> Self::SubProgress

Adds a new child, whose parent is this instance, with the given name.

This will make the child progress to appear contained in the parent progress. Note that such progress does not have a stable identifier, which can be added with [add_child_with_id()][Progress::add_child_with_id()] if desired.

fn add_child_with_id( &mut self, name: impl Into<String>, id: [u8; 4], ) -> Self::SubProgress

Adds a new child, whose parent is this instance, with the given name and id.

This will make the child progress to appear contained in the parent progress, and it can be identified using id.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
