Struct toml::de::Deserializer

impl<'a> Deserializer<'a>

pub fn new(input: &'a str) -> Deserializer<'a>

Creates a new deserializer which will be deserializing the string provided.

pub fn end(&mut self) -> Result<(), Error>

The Deserializer::end method should be called after a value has been fully deserialized. This allows the Deserializer to validate that the input stream is at the end or that it only has trailing whitespace/comments.

pub fn set_require_newline_after_table(&mut self, require: bool)

Historical versions of toml-rs accidentally allowed a newline after a table definition, but the TOML spec requires a newline after a table definition header.

This option can be set to false (the default is true) to emulate this behavior for backwards compatibility with older toml-rs versions.

pub fn set_allow_duplicate_after_longer_table(&mut self, allow: bool)

Historical versions of toml-rs accidentally allowed a duplicate table header after a longer table header was previously defined. This is invalid according to the TOML spec, however.

This option can be set to true (the default is false) to emulate this behavior for backwards compatibility with older toml-rs versions.
