pub struct Header<C: HeaderChecker> { /* private fields */ }
Expand description

A file header to check for, or add to, files.

Implementations§

source§

impl<C: HeaderChecker> Header<C>

source

pub fn new(checker: C, header: String) -> Self

Construct a new Header with the checker used to determine if the header is already present, and the plain header text to add.

header does not need to have applicable comment syntax, etc, as that will be added for each file type encountered.

source

pub fn header_present(&self, input: &mut impl Read) -> Result<bool>

Return true if the file has the desired header, false otherwise.

source

pub fn add_header_if_missing(&self, p: &Path) -> Result<bool, AddHeaderError>

Add the header, with appropriate formatting for the type of file indicated by p’s extension, if the header is not already present. Returns true if the header was added.
