pub fn with_flags(self, flags: Flags) -> Result<Self>

pub fn empty() -> Self

pub fn format(&self) -> &str

returns the format of this schema.

pub fn name(&self) -> &str

returns the name of this schema.

pub fn flags(&self) -> Option<Flags>

pub fn child(&self, index: usize) -> &Self

pub fn children(&self) -> impl Iterator<Item = &Self>

pub fn nullable(&self) -> bool
