Trait TomlValueSetExt

pub trait TomlValueSetExt {
    // Required method
    fn set_with_seperator(
        &mut self,
        query: &str,
        sep: char,
        value: Value,
    ) -> Result<Option<Value>>;

    // Provided method
    fn set(&mut self, query: &str, value: Value) -> Result<Option<Value>> { ... }
}

Required Methods

fn set_with_seperator( &mut self, query: &str, sep: char, value: Value, ) -> Result<Option<Value>>

Extension function for setting a value in the current toml::Value document using a custom seperator

Semantics

The function never creates intermediate data structures (Tables or Arrays) in the document.

Return value

• If the set operation worked correctly, Ok(None) is returned.
• If the set operation replaced an existing value Ok(Some(old_value)) is returned
• On failure, Err(e) is returned:
  • If the query is "a.b.c" but there is no table "b": error
  • If the query is "a.b.[0]" but “b" is not an array: error
  • If the query is "a.b.[3]" but the array at “b" has no index 3: error
  • etc.

Provided Methods

fn set(&mut self, query: &str, value: Value) -> Result<Option<Value>>

Extension function for setting a value from the current toml::Value document
