See the rustfmt documentation
for the descriptions of these stable and non-stable options.
Fields§
§max_width: Option<usize>Maximum width of each line
hard_tabs: Option<bool>Use tab characters for indentation, spaces for alignment
tab_spaces: Option<usize>Number of spaces per tab
newline_style: Option<NewlineStyle>Unix or Windows line endings
indent_style: Option<IndentStyle>How do we indent expressions or items
use_small_heuristics: Option<Heuristics>Whether to use different formatting for items and expressions if they satisfy a heuristic notion of ‘small’
fn_call_width: Option<usize>Maximum width of the args of a function call before falling back to vertical formatting.
attr_fn_like_width: Option<usize>Maximum width of the args of a function-like attributes before falling back to vertical formatting.
struct_lit_width: Option<usize>Maximum width in the body of a struct lit before falling back to vertical formatting.
struct_variant_width: Option<usize>Maximum width in the body of a struct variant before falling back to vertical formatting.
array_width: Option<usize>Maximum width of an array literal before falling back to vertical formatting.
chain_width: Option<usize>Maximum length of a chain to fit on a single line.
single_line_if_else_max_width: Option<usize>Maximum line length for single line if-else expressions. A value of zero means always break if-else expressions.
wrap_comments: Option<bool>Break comments to fit on the line
format_code_in_doc_comments: Option<bool>Format the code snippet in doc comments.
doc_comment_code_block_width: Option<usize>Maximum width for code snippets in doc comments. No effect unless format_code_in_doc_comments = true
