Struct toml::de::Deserializer [−][src]
pub struct Deserializer<'a> { /* fields omitted */ }
Expand description
Deserialization implementation for TOML.
Implementations
Creates a new deserializer which will be deserializing the string provided.
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.
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.
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.
