Struct ProviderMeta 

pub struct ProviderMeta {
    pub name: &'static str,
    pub display_name: &'static str,
    pub aliases: &'static [&'static str],
    pub supported_commands: SupportedCommands,
    pub build: ProviderFactory,
    pub check: Option<ProviderCheckFn>,
    pub command_flags: &'static [(StandardCommand, &'static [FlagDescriptor])],
    pub extension_commands: &'static [(&'static str, CommandDescriptor)],
}

Static metadata and factory for a single provider.

Stored in the registry; does not hold any live connections or state.

Fields

name: &'static str

Canonical name used as the primary --provider value.

display_name: &'static str

Human-readable display name shown in help and diagnostics.

aliases: &'static [&'static str]

All accepted --provider aliases, including the canonical name. Insertion order is preserved for deterministic --help output.

supported_commands: SupportedCommands

Which standard core commands this provider supports. Used to generate provider support tags in --help output.

build: ProviderFactory

Factory function — instantiates the provider from a ProviderConfig.

check: Option<ProviderCheckFn>

Optional health check function registered by the provider.

When Some, provider check calls this to verify connectivity and (where possible) authentication. When None, the check is skipped.

command_flags: &'static [(StandardCommand, &'static [FlagDescriptor])]

Provider-specific flags per standard command. Key is the standard command identifier for the target core command.

extension_commands: &'static [(&'static str, CommandDescriptor)]

Extension commands registered by this provider.

Each entry is a (signal, descriptor) pair where signal is the signal group the command belongs to (e.g. "trace", "metric"). Unlike command_flags (which uses StandardCommand identifiers), extension commands use a bare signal name because the command name itself lives in the descriptor.
