Struct artichoke::repl::PromptConfig

pub struct PromptConfig<'a, 'b, 'c> {
    pub simple: &'a str,
    pub continued: &'b str,
    pub result_prefix: &'c str,
}

Configuration for the REPL readline prompt.

Fields

simple: &'a str

Basic prompt for start of a new expression.

continued: &'b str

Altered prompt when an expression is not terminated.

result_prefix: &'c str

Prefix for the result of $expression.inspect. A newline is printed after the Ruby result.

Implementations

impl<'a, 'b, 'c> PromptConfig<'a, 'b, 'c>

pub const fn new() -> Self

Create a new, default REPL prompt.

Default configuration

The PromptConfig is setup with the following literals:

• simple: >>>
• continued: ...
• result_prefix: =>

Examples

let config = PromptConfig {
    simple: ">>> ",
    continued: "... ",
    result_prefix: "=> ",
};
assert_eq!(config, PromptConfig::new());
assert_eq!(config, PromptConfig::default());

Trait Implementations

impl<'a, 'b, 'c> Clone for PromptConfig<'a, 'b, 'c>

fn clone(&self) -> PromptConfig<'a, 'b, 'c>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a, 'b, 'c> Debug for PromptConfig<'a, 'b, 'c>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a, 'b, 'c> Default for PromptConfig<'a, 'b, 'c>

fn default() -> Self

Returns the “default value” for a type.

impl<'a, 'b, 'c> Hash for PromptConfig<'a, 'b, 'c>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a, 'b, 'c> Ord for PromptConfig<'a, 'b, 'c>

fn cmp(&self, other: &PromptConfig<'a, 'b, 'c>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl<'a, 'b, 'c> PartialEq for PromptConfig<'a, 'b, 'c>

fn eq(&self, other: &PromptConfig<'a, 'b, 'c>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a, 'b, 'c> PartialOrd for PromptConfig<'a, 'b, 'c>

fn partial_cmp(&self, other: &PromptConfig<'a, 'b, 'c>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
