Struct CmdLine 

pub struct CmdLine {
    name: String,
    contents: Vec<String>,
}

A CmdLine holds a set of command-line arguments that augment a configuration.

These arguments are formatted in toml, and concatenated into a single toml object. With arguments of the form “key=bareword”, the bareword is quoted for convenience.

Fields

name: String

String for decorating Values.

contents: Vec<String>

List of toml lines as given on the command line.

Implementations

impl CmdLine

pub fn new() -> Self

Make a new empty command-line

pub fn push_toml_line(&mut self, line: String)

Add a single line of toml to the configuration.

fn convert_toml_error( &self, toml_str: &str, error_message: &str, span: &Option<Range<usize>>, ) -> String

Try to adjust the contents of a toml deserialization error so that instead it refers to a single command-line argument.

fn build_toml(&self) -> String

Compose elements of this cmdline into a single toml string.

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

Formats the value using the given formatter.

impl Default for CmdLine

fn default() -> Self

Returns the “default value” for a type.

impl Provider for CmdLine

fn metadata(&self) -> Metadata
