Struct clap_cargo::Features

#[non_exhaustive]pub struct Features {
    pub all_features: bool,
    pub no_default_features: bool,
    pub features: Vec<String>,
}

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct {{ .. }} syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

all_features: bool

Activate all available features

no_default_features: bool

Do not activate the default feature

features: Vec<String>

Space-separated list of features to activate

Implementations

impl Features

pub fn forward_metadata<'m>(
    &self,
    meta: &'m mut MetadataCommand
) -> &'m mut MetadataCommand

Forward these flags to the cargo_metadata crate.

Note: Requires the features cargo_metadata.

Trait Implementations

impl Clone for Features

fn clone(&self) -> Features

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Features

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

Formats the value using the given formatter.

impl Default for Features

fn default() -> Features

Returns the "default value" for a type.

impl Eq for Features

impl PartialEq<Features> for Features

fn eq(&self, other: &Features) -> bool

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

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

This method tests for !=.

impl StructOpt for Features

fn clap<'a, 'b>() -> App<'a, 'b>

Returns clap::App corresponding to the struct.

fn from_clap(matches: &ArgMatches<'_>) -> Self

Builds the struct from clap::ArgMatches. It's guaranteed to succeed if matches originates from an App generated by StructOpt::clap called on the same type, otherwise it must panic.

pub fn from_args() -> Self

Builds the struct from the command line arguments (std::env::args_os). Calls clap::Error::exit on failure, printing the error message and aborting the program.

pub fn from_args_safe() -> Result<Self, Error>

Builds the struct from the command line arguments (std::env::args_os). Unlike StructOpt::from_args, returns clap::Error on failure instead of aborting the program, so calling .exit is up to you.

pub fn from_iter<I>(iter: I) -> Self where
    I: IntoIterator,
    <I as IntoIterator>::Item: Into<OsString>,
    <I as IntoIterator>::Item: Clone, 

Gets the struct from any iterator such as a Vec of your making. Print the error message and quit the program in case of failure.

pub fn from_iter_safe<I>(iter: I) -> Result<Self, Error> where
    I: IntoIterator,
    <I as IntoIterator>::Item: Into<OsString>,
    <I as IntoIterator>::Item: Clone, 

Gets the struct from any iterator such as a Vec of your making.

impl StructOptInternal for Features

fn augment_clap<'a, 'b>(app: App<'a, 'b>) -> App<'a, 'b>

fn is_subcommand() -> bool

pub fn from_subcommand(
    _sub: (&'b str, Option<&'b ArgMatches<'a>>)
) -> Option<Self>
