Enum Value

pub enum Value {
    Single(String),
    Array(Vec<String>),
}

A single value or a list of values declared in the output of the alpm-pkgbuild-bridge script.

Both parser functions ensure that at least one value exists.

Variants

Single(String)

A single value.

Array(Vec<String>)

An array of values.

Implementations

impl Value

pub fn as_vec(&self) -> Vec<&String>

Returns the values of &self in vector representation.

This is useful for values that may be available as both single values and arrays.

pub fn as_owned_vec(self) -> Vec<String>

Returns the values of self in vector representation.

This is useful for values that may be available as both single values and arrays.

pub fn has_value(&self) -> bool

Checks whether this holds a value.

Returns true if self is Value::Single (they always have a value set by definition), or if self is Value::Array and contains at least one element. Returns false in all other cases.

fn single_till_newline(input: &mut &str) -> ModalResult<Self>

Recognizes a Value::Single in a string slice while handling the surroundings.

Consumes leading and trailing spaces while also consuming newlines. Also allows variables at the end of the file where no newline is found. Calls Value::parse_next_value for variable parsing.

Errors

Returns an error if no Value::Single can be recognized in input.

fn list_till_newline(input: &mut &str) -> ModalResult<Self>

Recognizes a Value::Array in a string slice while handling the surroundings.

Consumes leading and trailing spaces while also consuming newlines. Also allows variables at the end of the file where no newline is found. Calls Self::parse_next_value for variable parsing.

Errors

Returns an error if no Value::Array is found in input.

pub fn parse_next_value(input: &mut &str) -> ModalResult<String>

Recognizes a Value::Single in a string slice.

Calls Value::variable_character to handle escaped characters in input.

Examples

"This is a string value\" with escaped \\ characters"

Errors

Returns an error if no Value::Single is found in input.

pub fn variable_character(input: &mut &str) -> ModalResult<char>

Recognizes a single char in a string slice.

This allows for detecting escaped characters, such as \" or \\.

Consumes a single character and returns afterwards.

Errors

Returns an error if a stand-alone " or \ is encountered.

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.
