Module utils 

Assorted functions shared by several assists.

Modules

gen_trait_fn_body 🔒

This module contains functions to generate default trait impl function bodies where possible.

ref_field_expr 🔒

This module contains a helper for converting a field access expression into a path expression. This is used when destructuring a tuple or struct.

Functions

add_group_separators 🔒

add_trait_assoc_items_to_impl

Given original_items retrieved from the trait definition (usually by filter_assoc_items()), clones each item for update and applies path transformation to it, then inserts into impl_. Returns the modified impl_ and the first associated item that got inserted.

check_pat_variant_from_enum 🔒

check_pat_variant_nested_or_literal_with_depth 🔒

convert_param_list_to_arg_list 🔒

Convert a list of function params to a list of arguments that can be passed into a function call.

convert_reference_type 🔒

could_deref_to_target 🔒

cover_edit_range 🔒

cover_let_chain 🔒

does_pat_match_variant 🔒

does_pat_variant_nested_or_literal 🔒

expr_fill_default 🔒

extract_trivial_expression

filter_assoc_items

find_struct_impl 🔒

find_struct_impl looks for impl of a struct, but this also has additional feature where it takes a list of function names and check if they exist inside impl_, if even one match is found, it returns None.

generate_impl 🔒

generate_impl_inner 🔒

generate_impl_with_item 🔒

Generates the corresponding impl Type {} including type and lifetime parameters.

generate_trait_impl 🔒

Generates the corresponding impl <trait> for Type {} including type and lifetime parameters, with <trait> appended to impl‘s generic parameters’ bounds.

generate_trait_impl_intransitive 🔒

Generates the corresponding impl <trait> for Type {} including type and lifetime parameters, with impl‘s generic parameters’ bounds kept as-is.

generate_trait_impl_intransitive_with_item 🔒

generate_trait_impl_with_item 🔒

generic_param_associated_bounds 🔒

replace_record_field_expr 🔒

Replaces the record expression, handling field shorthands including inside macros.

required_hashes 🔒

Calculate the number of hashes required for a raw string containing s

string_prefix 🔒

Calculate the string literal prefix length

string_suffix 🔒

Calculate the string literal suffix length

test_related_attribute_syn

This is a method with a heuristics to support test methods annotated with custom test annotations, such as #[test_case(...)], #[tokio::test] and similar. Also a regular #[test] annotation is supported.

trimmed_text_range 🔒

Trim(remove leading and trailing whitespace) initial_range in source_file, return the trimmed range.

tt_from_syntax 🔒

Creates a token tree list from a syntax node, creating the needed delimited sub token trees. Assumes that the input syntax node is a valid syntax tree.

wrap_block 🔒

wrap_paren 🔒
