A text element that has a size and can be rendered to the terminal.

Required Methods

fn size(&self, parent: Constraint) -> Size

Get the size of the element, in rows and columns.

fn render(&self, parent: Constraint) -> Vec<Line>

Render the element as lines of text that can be printed.

Provided Methods

fn columns(&self, parent: Constraint) -> usize

Get the number of columns occupied by this element.

fn rows(&self, parent: Constraint) -> usize

Get the number of rows occupied by this element.

fn print(&self)

Print this element to stdout.

fn write(&self, constraints: Constraint) -> Result<(), Error>

where Self: Sized,

Write using the given constraints to stdout.

fn display(&self, constraints: Constraint) -> String

Return a string representation of this element.

Trait Implementations

impl Element for Box<dyn Element + '_>

fn size(&self, parent: Constraint) -> Size

Get the size of the element, in rows and columns.

fn render(&self, parent: Constraint) -> Vec<Line>

Render the element as lines of text that can be printed.

fn print(&self)

Print this element to stdout.

fn columns(&self, parent: Constraint) -> usize

Get the number of columns occupied by this element.

fn rows(&self, parent: Constraint) -> usize

Get the number of rows occupied by this element.

fn write(&self, constraints: Constraint) -> Result<(), Error>

where Self: Sized,

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
