Module rust 

rust literal encoders.

encodes untrusted strings for safe embedding in rust source literals.

• for_rust_string — safe for rust string literals ("...")
• for_rust_char — safe for rust char literals ('...')
• for_rust_byte_string — safe for rust byte string literals (b"...")

encoding rules

all three encoders use rust’s native escape syntax:

• named escapes: \0, \t, \n, \r, \\
• C0 controls and DEL without named escapes → \xHH
• unicode non-characters → space (string/char) or \xHH per byte (byte string)

the encoders differ in which quote is escaped and how non-ASCII is handled:

encoder	quote escape	non-ASCII
for_rust_string	" → \"	passes through
for_rust_char	' → \'	passes through
for_rust_byte_string	" → \"	each UTF-8 byte → \xHH

Functions

for_rust_byte_string

encodes input for safe embedding in a rust byte string literal (b"...").

for_rust_char

encodes input for safe embedding in a rust char literal ('...').

for_rust_string

encodes input for safe embedding in a rust string literal ("...").

write_rust_byte_string

writes the rust-byte-string-encoded form of input to out.

write_rust_char

writes the rust-char-encoded form of input to out.

write_rust_string

writes the rust-string-encoded form of input to out.
