Module target_info

This modules contains types storing information of target platforms.

Normally, call RustcTargetData::new to construct all the target platform once, and then query info on your demand. For example,

• RustcTargetData::dep_platform_activated to check if platform is activated.
• RustcTargetData::info to get a TargetInfo for an in-depth query.
• TargetInfo::rustc_outputs to get a list of supported file types.

Structs

FileType

Type of each file generated by a Unit.

RustDocFingerprint

Structure used to deal with Rustdoc fingerprinting

RustcTargetData

Collection of information about rustc and the host and target.

TargetInfo

Information about the platform target gleaned from querying rustc.

Enums

FileFlavor

Kind of each file generated by a Unit, part of FileType.

Flags 🔒

Compiler flags for either rustc or rustdoc.

Functions

error_missing_print_output 🔒

Helper for creating an error message for missing output from a certain --print request.

extra_args 🔒

Acquire extra flags to pass to the compiler from various locations.

output_err_info 🔒

Helper for creating an error message when parsing rustc output fails.

parse_crate_type 🔒

Takes rustc output (using specialized command line args), and calculates the file prefix and suffix for the given crate type, or returns None if the type is not supported. (e.g., for a Rust library like libcargo.rlib, we have prefix “lib” and suffix “rlib”).

rustflags_from_build 🔒

Gets compiler flags from [build] section in the config. See extra_args for more.

rustflags_from_env 🔒

Gets compiler flags from environment variables. See extra_args for more.

rustflags_from_host 🔒

Gets compiler flags from [host] section in the config. See extra_args for more.

rustflags_from_target 🔒

Gets compiler flags from [target] section in the config. See extra_args for more.
