Trait Implementations

impl JsonSchema for Subcommands

fn schema_name() -> String

The name of the generated JSON Schema.

fn json_schema(gen: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl StructOpt for Subcommands

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.

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.

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][clap::Error::exit] is up to you.

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.

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 Subcommands

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

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

fn is_subcommand() -> bool
