Implementations

impl<W: Write> PropertiesWriter<W>

pub fn new(writer: W) -> Self

Writes to the given Write stream.

pub fn new_with_encoding(writer: W, encoding: &'static dyn Encoding) -> Self

Writes to the given Write stream in the given encoding. Note that the Java properties specification specifies ISO-8859-1 encoding for properties files; in most cases, new should be called instead.

pub fn write_comment(&mut self, comment: &str) -> Result<(), PropertiesError>

Writes a comment to the file.

pub fn write(&mut self, key: &str, value: &str) -> Result<(), PropertiesError>

Writes a key/value pair to the file.

pub fn flush(&mut self) -> Result<(), PropertiesError>

Flushes the underlying stream.

pub fn set_comment_prefix(
    &mut self,
    prefix: &str
) -> Result<(), PropertiesError>

Sets the comment prefix.

The prefix must contain a '#' or a '!', may only contain spaces, tabs, or form feeds before the comment character, and may not contain any carriage returns or line feeds ('\r' or '\n').

pub fn set_kv_separator(
    &mut self,
    separator: &str
) -> Result<(), PropertiesError>

Sets the key/value separator.

The separator may be non-empty whitespace, or a colon with optional whitespace on either side, or an equals sign with optional whitespace on either side. (Whitespace here means ' ', '\t', or '\f'.)

pub fn set_line_ending(&mut self, line_ending: LineEnding)

Sets the line ending.
