Crate awint_macro_internals
source · [−]Expand description
This crate exists because of limitations with proc-macro crates. We need
to be able to test errors returned from the code generation function while
also being able to test the macros themselves. This might also be reused by
people who have new storage types.
Structs
This is a special purpose structure that can efficiently handle forwards and
backwards lookups and maintains the set property. A is associated data
that is not hashed or used in equality comparisons.
For concatenation widths
Note: the type must be unambiguous for the construction functions
Prefixes used for codegen names and functions. Most of these should be prefixed with two underscores and the crate name to prevent collisions.
Usize and/or String Bound. If s.is_empty(), then there is no arbitrary
string in the bound and the base value is 0. x is added on to the value.
Enums
Bitwidth as described by a single value or one value minus another
Constants
Default names for awint
Traits
For results that have the same Ok and Err types
Functions
Input parsing and code generation function for corresponding concatenations of components macros.
Lowering of the parsed structs into Rust code.
Wrap s in ANSI delimiters for terminal colors.
{90..=97} => {grey, red, green, yellow, blue, purple, cyan, white}
Tries parsing as hexadecimal, octal, binary, and decimal
Tries to parse raw input as a range. Looks for the existence of top
level “..” or “..=” punctuation. If allow_single_bit_range is set, will
return a single bit range if “..” or “..=” does not exist.
In ranges we commonly see stuff like (x + y) or (x - y) with one of them
being a constant we can parse, which passes upward the Usb and Usbr
chain to get calculated into a static width.
Looks for the existence of a top level “[]” delimited group and uses the last one as a bit range.
Parses input TokenStream into “raw” concatenations of components in
Vec<char> strings
Returns architecture-independent Rust code that returns an
InlAwi preset with the value of bits.
Returns architecture-independent Rust code that returns an
InlAwi type with bitwidth bw.
