Struct ExtraCallerConfig 

pub struct ExtraCallerConfig {
    pub caller_name: String,
    pub import_sources: Vec<String>,
    pub namespace_arg_index: Option<usize>,
    pub fixed_namespace: Option<String>,
    pub namespace_option: Option<NamespaceOptionConfig>,
    pub static_replacement: String,
    pub dynamic_replacement: String,
}

Descriptor for a compat-adapter caller that the SWC plugin should recognise and rewrite in the same way as the native useIntlayer / getIntlayer calls (i.e. replace the string-key argument with a pre-imported dictionary object and swap the function name for a *Dictionary variant).

These are supplied entirely by the compat adapter plugins (e.g. createNextI18nPlugin) and are forwarded into the SWC config; no compat names are hard-coded inside this crate. The wire format is produced by toSwcExtraCallers in @intlayer/config/callers — both sides must stay in sync.

Exactly one of namespace_arg_index, fixed_namespace or namespace_option describes where the namespace (dictionary key) is read from; they are tried in that order.

Fields

caller_name: String

The function name the user calls, e.g. "useTranslation".

import_sources: Vec<String>

The import package specifiers that can export this function, e.g. ["react-i18next", "@intlayer/react-i18next"].

namespace_arg_index: Option<usize>

Zero-based index of the positional argument that holds the namespace (dictionary key) string, e.g. 0 for useTranslation('about').

fixed_namespace: Option<String>

Compile-time constant namespace — every call site reads the same dictionary; the dictionary ident is inserted as a new first argument (lingui’s useLingui() → useDictionary(_messages)).

namespace_option: Option<NamespaceOptionConfig>

Namespace read from a property of an options-object argument; the dictionary ident is inserted as a new first argument and the property is rewritten to the key-prefix remainder (or removed).

static_replacement: String

Name of the replacement function for static-import mode, e.g. "useTranslationDictionary".

dynamic_replacement: String

Name of the replacement function for dynamic/fetch import mode, e.g. "useTranslationDictionaryDynamic".
