Enum SthResult 

pub enum SthResult {
    Ok(SignedTreeHead),
    Err(Error),
    ErrWithSth(Error, SignedTreeHead),
}

Either a fetched and checked SignedTreeHead, or a SignedTreeHead that has a valid signature but did not pass some internal checks, or just an Error.

Variants

Ok(SignedTreeHead)

Got the new tree head.

Err(Error)

Something went wrong and no tree head was received.

ErrWithSth(Error, SignedTreeHead)

Something went wrong, but the server returned a valid signed tree head. The underlying error is wrapped inside. You may wish to log this.

Implementations

impl SthResult

pub fn tree_head(&self) -> Option<&SignedTreeHead>

Return a signed tree head, if there is one received.

This can return a Some even when there is error, if for example, the server returned a valid signed tree head but failed to provide a consistency proof. You may wish to log this.

pub fn is_ok(&self) -> bool

pub fn is_err(&self) -> bool

pub fn unwrap(self) -> SignedTreeHead

Return the SignedTreeHead, if this is a Ok. Otherwise panic.

pub fn unwrap_err(self) -> Error

Return the Error, if this is an Err or ErrWithSth. Otherwise panic.

pub fn unwrap_tree_head(self) -> SignedTreeHead

Return the SignedTreeHead, if this is a Ok or ErrWithSth. Otherwise panic.

Trait Implementations

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
