Struct design_pattern_examples_rust::command::command_textobject::CommandTextObject

pub struct CommandTextObject {
    starting_text: String,
    pub text: String,
}

Container for a string. Need to use a class that allows the text to be changed while the container (this class) remains constant. This way, operations can be applied to the text and the container’s contents change but not the container.

Fields

starting_text: String

Starting string text so we can reset the text to a known point.

text: String

The text that can change.

Implementations

impl CommandTextObject

pub fn new(text: &str) -> CommandTextObject

Parameters

• text
