# CcToolchainConfigInfo

{% dynamic setvar source_file "src/main/java/com/google/devtools/build/lib/starlarkbuildapi/cpp/CcToolchainConfigInfoApi.java" %} {% dynamic setvar version "7.4.0" %} {% dynamic setvar original_path "/rules/lib/providers/CcToolchainConfigInfo" %} {% include "_buttons.html" %} Additional layer of configurability for C++ rules. Encapsulates platform-dependent specifics of C++ actions through features and action configs. It is used to configure the C++ toolchain, and later on for command line construction. Replaces the functionality of CROSSTOOL file.

## proto

    string CcToolchainConfigInfo.proto

Returns CToolchain text proto from the CcToolchainConfigInfo data.

## to_json

    string CcToolchainConfigInfo.to_json()

Deprecated. This API is deprecated and will be removed soon. Please do not depend on it. It is disabled with `---incompatible_struct_has_no_methods`. Use this flag to verify your code is compatible with its imminent removal.
Creates a JSON string from the struct parameter. This method only works if all struct elements (recursively) are strings, ints, booleans, other structs, a list of these types or a dictionary with string keys and values of these types. Quotes and new lines in strings are escaped. Examples:

    struct(key=123).to_json()
    # {"key":123}

    struct(key=True).to_json()
    # {"key":true}

    struct(key=[1, 2, 3]).to_json()
    # {"key":[1,2,3]}

    struct(key='text').to_json()
    # {"key":"text"}

    struct(key=struct(inner_key='text')).to_json()
    # {"key":{"inner_key":"text"}}

    struct(key=[struct(inner_key=1), struct(inner_key=2)]).to_json()
    # {"key":[{"inner_key":1},{"inner_key":2}]}

    struct(key=struct(inner_key=struct(inner_inner_key='text'))).to_json()
    # {"key":{"inner_key":{"inner_inner_key":"text"}}}

.

Deprecated: instead, use json.encode(x) or json.encode_indent(x), which work for values other than structs and do not pollute the struct field namespace.

## to_proto

    string CcToolchainConfigInfo.to_proto()

Deprecated. This API is deprecated and will be removed soon. Please do not depend on it. It is disabled with `---incompatible_struct_has_no_methods`. Use this flag to verify your code is compatible with its imminent removal.
Creates a text message from the struct parameter. This method only works if all struct elements (recursively) are strings, ints, booleans, other structs or dicts or lists of these types. Quotes and new lines in strings are escaped. Struct keys are iterated in the sorted order. Examples:

    struct(key=123).to_proto()
    # key: 123

    struct(key=True).to_proto()
    # key: true

    struct(key=[1, 2, 3]).to_proto()
    # key: 1
    # key: 2
    # key: 3

    struct(key='text').to_proto()
    # key: "text"

    struct(key=struct(inner_key='text')).to_proto()
    # key {
    #   inner_key: "text"
    # }

    struct(key=[struct(inner_key=1), struct(inner_key=2)]).to_proto()
    # key {
    #   inner_key: 1
    # }
    # key {
    #   inner_key: 2
    # }

    struct(key=struct(inner_key=struct(inner_inner_key='text'))).to_proto()
    # key {
    #    inner_key {
    #     inner_inner_key: "text"
    #   }
    # }

    struct(foo={4: 3, 2: 1}).to_proto()
    # foo: {
    #   key: 4
    #   value: 3
    # }
    # foo: {
    #   key: 2
    #   value: 1
    # }

Deprecated: use proto.encode_text(x) instead.
